I ran across this looking for clips of Bill Murray and Christopher Guest on Howard Cosell's Saturday Night Live (I'd heard Murray talk about it briefly on one of the Times Talks podcasts (mp3).
This is not (I don't think..?) that (but it seems like it just has to be related somehow); it's a TVTV production: Bill Murray and Christopher Guest at the 1976 Superbowl.
Here's some context for TVTV: Fascinating?
Yes, I deem it: Fascinating.
Christopher Guest had nice hair!
Tune in tomorrow when I blather on and on about Z Channel.
