This is really incredibly lame, but older forum users will remember a 1970s ITV series called 'The Comedians'.
My mum and dad ran into a group of the regular participants during a day at the races in the early seventies, including Duggie Brown and Charlie Williams, and apparently they were all absolute gentlemen.
Compare this to Jimmy Tarbuck who told my mum to "piss off" when she approached him for an autograph in 1966.
I remember 'The Comedians' well. I think my dad used to book Duggie Brown for his club and found him okay. Never liked Tarbie.
