From Wikipedia:
Caesar's Hour was a television program that aired on NBC from 1954 until 1957. The program starred, among others, Sid Caesar, Nanette Fabray, Carl Reiner, and Milt Kamen, and featured a number of cameo roles by famous entertainers such as Joan Crawford and Peggy Lee.
Widely considered a continuation of Caesar's earlier program, Your Show of Shows, Caesar's Hour included most of the same writers and actors, with the notable addition of Woody Allen in the latter show. The writing staff of the show was legendary, and was reunited in 1996 for an event at the Writers Guild Theater in Los Angeles called Caesar's Hour Revisited excerpts of which were broadcast on PBS under the title Caesar's Writers.
A much more complete edit of the evening was made available on VHS tape, but has never been reissued on DVD. It featured Caesar with Mel Tolkin (head writer), Neil Simon, Danny Simon, Mel Brooks, Carl Reiner, Larry Gelbart, Sheldon Keller, Aaron Ruben, and Gary Belkin. The moderator and researcher was Bob Claster.
Like Your Show of Shows, most of the original recordings of Caesar's Hour were destroyed by NBC, so few copies remain. Over 40 fragments from the series survive at the UCLA Film and Television Archive.
