In 1972, the concept of a music television show designed to keep people glued to their television sets in the middle of the night was novel. In fact, it was so unusual that, according to various interviews with the Burt Sugarman, the veteran TV producer funded The Midnight Special himself to get the pilot on the air. That initial episode aired at 1 a.m. and featured performances from War, Linda Ronstadt, The Isley Brothers and more. The format was a hit and The Midnight Special ran until 1981. Today, there is plenty of footage to watch online and multiple DVD sets available, all of which serve as a 1970s time capsule. If you watch enough clips from The Midnight Special— and, trust me, I have— you’ll see the decade evolve from funky hippies to disco to new wave.

On The Midnight Special, viewers could check out artists from across genres. T. Rex, Kraftwerk, Minnie Riperton, The Doobie Brothers and Dolly Parton are just a few who appeared on the show. Here, though, I’m focusing on the disco clips you need to see. Check them out below.
