[first words in the first widely-seen talking picture]
Jack Robin: Wait a minute, wait a minute. You ain't heard nothin' yet! Wait a minute, I tell ya! You ain't heard nothin'! You wanna hear "Toot, Toot, Tootsie"? All right, hold on, hold on...
[walks back to one of the band members]
Jack Robin: Lou, listen. Play "Toot, Toot, Tootsie", three chorus, you understand. In the third chorus, I whistle. Now give it to 'em hard and heavy, go right ahead.
