Yes Sir, That's My Baby (song)
"Yes Sir, That's My Baby" is a popular U.S. song from 1925. The music was written by Walter Donaldson and the lyrics by Gus Kahn. It is now in the public domain. Background
The chorus begins, "Yes sir, that's my baby, no sir, don't mean maybe. Yes sir, that's my baby now." According to one source, the song was written when Donaldson and Kahn were visiting Eddie Cantor. Cantor's daughter Marjorie brought out one of her favorite toys, a walking mechanical pig. She wound it up and it started walking in rhythm while two notes kept coming from the little creature. Kahn was inspired and started working lyrics to these notes in rhythm with the pig, coming up with the title and opening line of the chorus in short order. 1925 recordings
