"We Got It" is the final song from the first act of the musical Over Here!, which opened on Broadway at the Shubert Theatre (Broadway) on March 6, 1974. The song was written by Robert B. Sherman and Richard M. Sherman.
Placement in the storyline
The "DePaul Sisters" (played by the Andrews Sisters) could not function as a singing act because they were only a duet. What they were missing throughout the first act was a third singer. (This plot device mirrors the Andrews Sisters' real life tragic dilemma of LaVerne Andrews death in 1967 which by default broke up their singing group.) By the addition of Mitzi to the group, they had their third singer and were on their way to the "big time". It is at this point in the plotline that "We Got It" is performed.
