My friend Michael turned me on to this show, which has just been added to Hulu. It's Joan River's 1968 syndicated talk show. Each half hour episode featured a different subject ranging from men's shirts to boating safety and included a monologue on the subject, an expert and a celebrity guest. Guests included June Havoc, Shecky Green, Joel Gray, Donald Pleasence and in the episode below, Lily Tomlin.
This episode covers the subject of stand-up comedy and how new talent is nurtured in the business. Lily Tomlin was then playing in night clubs in the village and had yet to break out on Laugh In. There are lots of episodes to choose from over at Hulu, I recommend the show for it's curious, sixties TV quality and the opportunity to see Joan Rivers and her celebrity guests back then.
Obscurity factor: 9 (largely forgotten, not on DVD, available on Hulu)
