Some things I've noticed are:
1 Jason Stephens has a higher profile and is involved in more things than in Series 2. I wonder why. Was he starting his production career at the same time and was therefore less available when Series 2 came around?
2 Tony Martin seems to involved in just about everything.
3 a lot of the material would simply not be allowed these days - but of course that applies to a lot of the comedy of the time.
4 am I the only person who thinks Santo Cilauro is the weakest link in the chain? He has a very limited range of characters. Perhaps he's better as a writer than a performer.
5 Jane Kennedy is an absolute star.
