 "Rock Island" from Meridith Wilson's "The Music Man" is wholly spoken by an ensemble of travelling salesmen, as are most of the numbers for British actor Rex Harrison in the 1964 Lerner and Loewe musical My Fair Lady.Glenn Miller's "The Lady's in Love with You" and "The Little Man Who Wasn't There" (both 1939), each contain distinctly rap-like sequences set to a driving beat as does the 1937 song "Doin' the Jive".In musical theater, the term "vamp" is identical to its meaning in jazz, gospel, and funk, and it fulfills the same function.
