Michael Keaton on Evening At The Improv 1980s

I'm currently transferring several tapes containing only stand-up comedians taped from late night TV in the 80s. I'm not into stand-up comedy myself, and don't know much about it, but many of these clips aren't otherwise available on Youtube so I figure I might as well post them. Some of them will be duplicates because the person who taped them sometimes taped the same routine during a rerun.
