David: Music always came first. I never set out to be an actor.
David: One of the things that set Starsky and Hutch apart from other shows was that we grew up with a generation, in a much simpler time, a time when there were fewer channels and the family would gather round and watch a particular show together.
David: I'm still close friends with Starsky, Paul Michael Glaser... Once, Paul and I had to re-shoot one scene 67 times because we kept looking at each other and laughing whenever the camera was switched on. It happens on stage sometimes, but luckily the audience are very forgiving!
