Gezorninplatz!

40 years ago I watched perhaps the least-funny comedy show I have ever seen. Oddly I can't find an entry on IMDB for it. The only mention I can find on the Web is the TV listings of the 'New York Times' for 1977 January 18:

'4) GEZORNINPLATZ:Comedy special. Kenny Mars, Bill Daily, Barbara Sharma, Jim Backus, Vicki Lawrence, Norm Crosby'

Does anyone else remember this show?
