Did you ever see the David Letterman show? Paul Schaffer, the keyboardist and bandleader on the show is a great example of that. Before Letterman, he played piano on Saturday Night Live.

Paul was an improviser, musically and comedically. Some word or concept Dave was riffing on would catch something in Paul and out would come related (often hilarious) music. On SNL, he and Bill Murray did a great lounge pianist/singer duo, playing off one another and obviously not entirely rehearsed.

I'll let you dig for links to that stuff. The digging is probably more fun than some presented example in this case.
