"I've Got Your Number" is a popular song composed by Cy Coleman with lyrics by Carolyn Leigh for the 1962 musical Little Me.
It was originally introduced by Swen Swenson and Virginia Martin in the show.
[1] American Theatre editor-in-chief Rob Weinert-Kendt wrote of the song in 2020, "It's got a sharp lyric by Carolyn Leigh and a wonderfully sneaky chart by Cy Coleman, a jazzman who happened to write for the musical theatre.
The key to its success is in its marriage of those two elements; it's a song about essentially cornering someone, not with hostility or predation but with a certain teasing knowingness, as if to say, 'Drop the act, I'm onto you, we belong together,' and the song's harmonic structure keeps enacting a sort of unflustered, don't-change-the-subject move.
[3] It was also sung and danced by Dick Van Dyke and Mary Tyler Moore on "The Alan Brady Show Goes to Jail," a 1964 episode of The Dick Van Dyke Show.
