Ain't She Sweet - written by Milton Ager (music) and Jack Yellen (lyrics) in 1927. Recorded by many artists, including the early Beatles, who were not yet moptops and wore their hair in what was called a d.a. (duck's ass) cut. They were recorded doing the song on June 22, 1961 in Hamburg, Germany, with Pete Best--not Ringo--on drums. (A Youtube of that performance exists, but I couldn't get a link that would register here.)*
*I wrote this post to follow "Sweet Music Man" but didn't get it in fast enough.
