The Tonight Show.

Cosby began his stand up routine in either 1961 or 62 when Jack Parr was still hosting.











Also I wonder if those Episodes with Cosby guest hosting for Carson exists today?







I know that the vast majority the episodes of Carson's first 10 years on the Tonight Show were erased.







Videotape was expensive back then and I guess it just didn't make sense to save a bunch of episodes that they knew wouldn't be repeated.







It's very rare to see such shows in reruns.
