I watched 120 Minutes almost every week but I really loved the show that existed a couple of years prior to 120 Minutes, The Cutting Edge. It was shown once a month and usually hosted by the Fleshtones, Peter Zremba. Since it was sponsored by IRS records, it catered to bands on that label. But they covered everybody, from the Minutemen to poetry reading from Lydia Lunch. A big influence on my listening habits.
It also warms my heart to see Night Flight get mentioned. When that show first began it would run from midnight to 6 AM every Saturday! I distinctly remember them showing plenty of cult movies and off-beat music videos from Some Bizzare.
