From Beatles Anthology DVD.
"Ain't She Sweet" is a song composed by Milton Ager and Jack Yellen in 1927. It became popular in the first half of the twentieth century, one of the smash hit songs that typified the Roaring Twenties. Like "Happy Days Are Here Again" (1929), it became a Tin Pan Alley standard. Both Ager and Yellen were elected to membership in the Songwriters Hall of Fame.
"Oh ain't she sweet, well see her walking down that street. Yes I ask you very confidentially: ain't she sweet? Oh ain't she nice, well look her over once or twice. Yes I ask you very confidentially: ain't she nice? Just cast an eye in her direction. Oh me oh my, ain't that perfection? Oh I repeat, well don't you think that's kind of neat? Yes I ask you very confidentially: ain't she sweet?".
Milton Ager wrote "Ain't She Sweet" for his daughter Shana Ager, who later grew up and became Shana Alexander, who was on television and on radio as a political commentator.
