Lippa was born in Leeds, England. to English parents. He emigrated to the US in October, 1967 and grew up in Oak Park, Michigan, a suburb of Detroit. He attended Oak Park High School in Oak Park, Michigan. While at the University of Michigan, Lippa studied vocal performance but eventually transferred into music education and received his bachelor's degree in music education. After graduating from Michigan, Lippa moved to New York City in 1987 and became a middle school music teacher at Columbia Grammar and Prep School (CGPS) on the Upper West Side. He was promoted his second year at (CGPS) to dean of 7th and 8th grade students – an assistant principal position – and held that post, in addition to teaching music, until June 1991. In 1988 Lippa was accepted into the celebrated BMI/Lehman Engel Musical Theatre Workshop as a composer. There he met his future collaborator Tom Greenwald (John & Jen). He later pursued a career in musical composition.
Lippa began his professional theatrical career at the Goodspeed Opera House in East Haddam, Connecticut. He was hired in early 1992 to be the pianist for a production of "It's a Bird... It's a Plane... It's Superman" but quickly rose to become the dance arranger and assistant music director. He then stayed on for the remainder of the season in that capacity. Following the Goodspeed, Lippa worked at various theatres as music director and/or pianist in addition to being an increasingly in-demand arranger.
The Goodspeed produced Lippa’s first musical, John & Jen (book by Tom Greenwald) in 1993 at The Norma Terris Theatre in Chester, Connecticut. What followed that production was a workshop production the following year at the Berkshire Theatre Festival and, ultimately, a nearly 6-month run at Lamb's Theatre in New York City. The show was produced by Carolyn Rossi Copeland.
Lippa then went on to write the book, music and lyrics for The Wild Party. He began work in 1996, and the Manhattan Theatre Club presented a reading of the first act later that year. Julia Murney, who later played the role of Queenie, was in the ensemble of that reading. The Wild Party had a two-week development at The Eugene O'Neill Theater Center in Connecticut in the summer of 1997. Following that period, producers Jeffrey Seller and Kevin McCollum optioned the play and, with the Manhattan Theater Club, made plans for production. The Wild Party was given its world premiere in 2000 at the off-Broadway Manhattan Theatre Club in New York City. The Wild Party won the Outer Critics Circle Award for best Off-Broadway musical of the season and Lippa won the 2000 Drama Desk Award for best music. The show was nominated for 13 Drama Desk Awards including best new musical.
In 1999, Lippa contributed three new songs to the Broadway version of You're a Good Man, Charlie Brown (including "My New Philosophy" for Kristin Chenoweth), and created all new arrangements. The other two songs were “Beethoven Day” and the new version of the title song. Lippa also produced the original cast recording and was honored with a Grammy nomination for his work on that recording.
In 2001, Lippa joined with Brian Crawley to create A Little Princess as a musical. That show later premiered in the summer of 2004 at TheatreWorks in Palo Alto, California. The recording was released on September 13, 2011 on Ghostlight Records. Texas State University’s musical theatre department under the direction of Kaitlin Hopkins presented the show in a revised version in concert with Lippa conducting October 16–19. Following that production, Music Theatre International (MTI) made the title available for license to theatres all over the world.
In 2006, the musical Asphalt Beach, with music and lyrics by Lippa and the book by T. C. Smith and Peter Spears premiered at the American Music Theatre Project at Northwestern University. Producer Stuart Oken produced that show and then asked Lippa to write the music and lyrics for The Addams Family. Lippa was honored with a Tony nomination (Best Original Score) and two Drama Desk nominations for his work on The Addams Family (book by Marshall Brickman and Rick Elice). The Addams Family starred Nathan Lane and Bebe Neuwirth, broke attendance records in Chicago during its 2009 try-out, and by its closing on December 31, 2011, had played 725 regular performances and 34 previews at the Lunt-Fontanne Theatre on Broadway. The US national tour begins in New Orleans in September, 2011. Planned international productions include São Paulo (March, 2012), Scandinavia (summer, 2012), London (autumn, 2012), an 18-month tour of Australia (beginning March 2013), and more to be announced shortly. The recording was released on Decca Broadway and the vocal selections are available from Hal Leonard.
Big Fish, Lippa’s newest musical, with a book by John August, based on the 2003 film and the 1998 novel, premiered in Chicago, Illinois at the Oriental Theatre from April 2013 through May 5, 2013. It opened on Broadway at the Neil Simon Theatre October 6, 2013, following previews that began on September 5, 2013. Susan Stroman directed and choreographed, with scenic design by Julian Crouch, costume design by William Ivey Long and lighting design by Donald Holder. Norbert Leo Butz starred as Edward Bloom with Kate Baldwin as Sandra and Bobby Steggert as Will.
In 1998, Lippa was commissioned by the Jewish Federation of Greater Vancouver to create an anthem for a concert celebrating Israel's 50th birthday, to be sung by 350 singers and conducted by Sergiu Comissiona of the Vancouver Symphony Orchestra.
As a singer, Lippa has performed at Carnegie Hall, Town Hall, The Rainbow Room, and The Supper Club. His vocal arrangements and singing can be heard in the songs of Stephen Schwartz in the animated feature, The Prince of Egypt.
He has acted as Kristin Chenoweth's music director since 1999  and has conducted and played Chenoweth's concerts at the Metropolitan Opera House (January 2007), the San Francisco Symphony (2005), Carnegie Hall (2004), and the Donmar Warehouse (2002), among others. Lippa wrote the music to the "Intervention Song" for Chenoweth's funnyordie.com video.
For Halloween weekend, 2011, the Harrisburg Symphony Orchestra under the baton of Stuart Malina premiered The Addams Family Casket of Orchestral Grotesqueries, a symphonic suite from Lippa's musical The Addams Family, arranged by Lippa and Larry Hochman and orchestrated by Hochman. That same weekend The New Mexico Gay Men’s Chorus, under the direction of Aaron Howe, premiered Lippa’s “Move Toward The Darkness” from The Addams Family in a new choral arrangement by Lippa’s frequent collaborator Mary-Mitchell Campbell.
A show called Jerry Christmas (book by Daniel Goldfarb) was produced by New York Stage and Film in 2007 but has since been shelved.
Another show called The Man in the Ceiling (book by Jules Feiffer), developed by Disney Theatrical and Tom Schumacher had two readings in 2008. Lippa hopes to return to this some day but has shelved it for the moment.
In 2012, the San Francisco Gay Men's Chorus and several other gay men's choruses commissioned Lippa to write a musical tribute to the life and legacy of Harvey Milk. The resulting 60-minute oratorio, entitled I Am Harvey Milk and starring Lippa himself as Harvey Milk, premiered at San Francisco's Nourse Theatre on June 26, 2013—the same day on which the U.S. Supreme Court declared Section 3 of DOMA and California Proposition 8 unconstitutional.
In November 2013, Andrew made his London debut with two concert performances at the St James Theatre, London. Produced by James Yeoburn and Stuart Matthew Price of United Theatrical, the concert featured guest performances from Ashleigh Gray, Carrie Hope Fletcher, Jenna Russell, Tam Mutu and Willemijn Verkaik. The concert exclusively previewed music from Andrew's latest Broadway musical Big Fish as well as a host of his more familiar and lesser known works, including I am Harvey Milk, The Addams Family and The Man in the Ceiling.
