 The A&R man on the first 1940 session insisted that we have no singing, but while he was out to lunch, we had Billy sing a couple of songs. The engineer was very nice about it and recorded them. We've been playing the numbers on one-nighters, so we didn't need any music. After the session was over, the engineer asked the A&R man to listen. "'What do you think of that?' he said after he played aside."
