Really good quote from this NPR interview.
"If you do one show a year or one show every three months or one show every four months, you have an awful lot of time to realize what a failure you've been," he said. "But we do kind of a baseball season: We do a show one night and we hope it's wonderful, and if not that, we hope it's good and we hope it isn't bad. But even if it's a great show or even if it's not such a good show, we do another show the next night and we have no time, except in self analysis, to decide why it wasn't good or even why it was very good."
