“I remember the one time Jolson visited the set, I was doing a number. And he said, kid, you're moving around too much. So he did the song. And he did everything except bang from the rafters. He had pre-recorded all the songs before the script was ready, and sang every one as if he were going to drop dead at the end of it. Well, that was Jolson. He always sang like that, which was why people loved him. But it was difficult from an actor's point-of-view. In one scene I was supposed to be singing as loudly as I could one second and then collapse in the middle of the song. How do you taper off at the top of your lungs?”
