I loved this show as a small child and grew up with my parents telling me how I often used to quote Aunty Jack's catch-phrase, "I'll rip your bloody arms off" with glee. Unfortunately watching it now as an adult I can't see how it would appeal to anyone apart from small children.
At best it's a pale imitation of Monty Python or the Goon Show, but even that's stretching it as there are simply no jokes in this show. Much is made of the musicality of the cast members in the liner notes for the dvd release but really, the musical numbers aren't good enough to stand up on their own, nor are they funny enough to work as comedy bits.
The overall standard is of a high school production, and even then I think maybe students might have more energy to make up for their lack of experience.
The only good thing I can think of about this show is that it must have pioneered the way for later comedians and performers who were actually funny.
