I did a 10 minute stand-up comedy act for a theater in downtown St. Petersburg, FL that was converted to have live acts in 1991. There was me and about 7 other comics. A local cable TV production company filmed it. It's on YouTube: https://www.youtube.com/watch?v=6Df_PrgdG-s.
Also in 1992/3 I was with an Improvisation group in Indianapolis that was on our local cable show, it too is on YouTube:
