I have just noticed recently how Glenda`s accent had changed from the early days.She seemed to have a broader,more working class accent in her earlier years than later on.Maybe it changed when Barry started to work for the building society.But I suppose due to the longevity of the series,all the regular characters changed and evolved to some extent.In the first two series I`ve noticed that Clegg was much more assertive and at times was (almost) arrogant.That`s not to say he was any less likable then,he was always my favourite from day one.
