Al Jolson
Wait a minute, wait a minute. You ain't heard nothin' yet—you ain't heard a thing. And now, ladies and gentlemen, I'm gonna sing you a little song that the ruler folks love to hear me sing. It's a little mammy song. And, very funny thing—people have been making fun of mammy songs, and I don't really think that it's right that they should. Why, after all, mammy songs are the fundamental songs of our country. And, not only that, you take John McCormack. John McCormack, the famous radio singer—he sings "Mother Machree", and that's a merry song. And folks, he ain't bad. So if you don't mind, I'm gonna sing you my little mammy song—"Rock-a-Bye Your Rock-a-Bye Baby with a Dixie Melody", if you please.
