Yes Sir, That's My Baby Ricky Nelson (#34 in 1960)

Yes sir, that’s my baby
No sir, I don’t mean maybe
Yes sir, that’s my baby now
 
Yes, ma’m, we’ve decided
No ma’m, we ain’t gonna hide it
Yes, ma’m, you’re invited now
 
By the way, by the way
When we walk up to the preacher I’ll say
 
Yes sir, that’s my baby
No sir, I don’t mean maybe
Yes sir, that’s my baby now
