"Dream Drummin'" followed by "Soft Music" are songs by Richard & Robert Sherman. They are from the musical Over Here!, which opened on Broadway at the Shubert Theatre (Broadway) on March 6, 1974. The songs segue from one to the next and then back again. The two song medley features John Travolta and the Andrews Sisters on lead vocals and the rest of the cast on backing vocals.
