Now that we get the Comedy Channel on Cable here I have watched some of the old Golden Years of Television shows - great memories.
One of these is the Abbot and Costelo show. Some people have said Jerry modelled some of his show after theirs. There certainly is a similarity.
The show started and ended with a 'Monologue', There was the interplay with neighbours and sessions in the Coffee Shop. Also it was generally about nothing: i.e. no real plot or conflict to resolve in 30 minutes.
Neat.
