The music was written by Walter Donaldson and the lyrics by Gus Kahn. It was a hit for Ace Brigode in 1925 and for Eddie Cantor in 1930. It was later a hit for Rick Nelson in the 1950s and Frank Sinatra in the 1960s. The song has become a standard that has been recorded by over 100 artists in genres from jazz to rock, marimba and country.
Opening line: "Yes sir, that's my ba - by, no sir, don't mean may - be, Yes sir, that's my ba - by now...."
According to one source, the song was written when Donaldson & 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 2 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.
A Yiddish version entitled "Yes Sir, Iz May Kalleh" [Yes Sir, That's My Bride] was recorded by Peisachke Burstein.
