Yes Sir, That's My Baby (song)
The music was written by Walter Donaldson and the lyrics by Gus Kahn. It was introduced by Margaret Young and was a hit for Ace Brigode in 1925 and for Eddie Cantor in 1930. It was later a hit for Ricky Nelson in 1960 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 of the chorus: "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 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.
A Yiddish version entitled "Yes Sir, Iz May Kalleh" (Yes Sir, That's My Bride) was recorded by Peisachke Burstein. In German the song was titled "Küss' mich, Schnucki-Putzi."
The song was sung in Italian by Duo Fasano (Fasano sisters duo)  and the famous Italian singer Raffaella Carrà in 1973. The song was titled "Lola" and talks about a girl (Lola) that the singer is convincing to dance the Charleston.
It was also remade by a Czech group Verona in 2011 with completely new lyrics and named "Hey Boy", becoming a holiday hit on local radio stations. Czech and Slovak listeners know the song from the traffic-information programm "Pozor, zákruta" (Watch out, turning), which has been broadcast since 1966 by Czechoslovak Radio, which took the instrumental version of that song as its signature.
The Swedish band Onkel Kånkel recorded a version of the song called Spetälske Leffe (Leprous Leffe) for their 1990 album Kalle Anka Suger Pung.
