This song was introduced by none other than William Frawley, best known as Fred Mertz on the television series I Love Lucy. (Frawley also introduced “Melancholy Baby,” among other songs!) Publisher Saul Borne brought it to Jolson, who interpolated it into the musical Bombo in 1921 and also sang it in The Jazz Singer and then in The JolsonStory. That same year, he recorded it for Decca and sold over a million copies. Jolson famously sang the song down on one knee, launching a million imitations.
