I saw this on the blog of my pal Paul Harris and decided it belonged here, too. It's a video from the mid-seventies (around early '77, I'd say) — excerpts from a local talk show in the midwest. The guests were all new, up-and-coming stand-up comedians discussing what their lives were like and this video has been edited to focus on one of them, a new kid named Dave Letterman. The other two are Dottie Archibald and Gary Muledeer. I dunno what's happened with Ms. Archibald but Muledeer is still out on the road touring and performing, usually as the opening act for Johnny Mathis.
At the end, Letterman is asked about how he feels about performing sans pay, which was then the norm at most comedy clubs. It would not be the norm for long.
