Ah, those early black-and-white Carry Ons have a charm all their own... I don't think it was till Carry on Spying maybe that they got the formula down pat... Carry on Sergeant - not only does it have Hartnell (who's great in it!), but bizarrely a very young-looking Bob Monkhouse as well!! My favourite Carry On is either Up the Khyber, or Carry On Screaming, as the mood takes me...
