Actors need bricks to play with, and in fact we rejected all the improvised fragments we had made without a plan. Improvisation without a plan is like tennis without tennis balls.
Only a fool does not fear actors, but you can't beat them, and if you can't beat them, join them, as they say. As I've got older I've become very interested in that part of the work.
It made me alive to the fact that the most important thing sometimes is what isn't said - to prepare for moments of revelation that can be read entirely on actors' faces without dialogue.
Only one of us would usually sing lead. Which most of the time was, Mickey or Dave. They thought it was perfectly a natural routine, because Mickey and Dave saw themselves as TV actors.
