From the wiki: “‘Ain’t She Sweet’ was composed by Milton Ager (music) and Jack Yellen (lyrics). Ager wrote the song for his daughter Shana Ager, who in her adult life was known as the political commentator Shana Alexander. ‘Ain’t She Sweet’ became popular in the first half of the 20th century as one of the 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 later elected to membership in the Songwriters Hall of Fame.
