I'm sure I remember seeing the old CBL logo in the background on beer pumps, ice recepticles, etc in pub/club scenes in some 80s episodes of 'Minder', 'OFAH', etc, which is one of many epitomes of the era.
I also recall a rather hilarious episode of Grange Hill from 1989 where the pupil character Trevor Cleaver smuggled a stash of cans of CBL onto the IOW trip and ended up passing out absolutely legless on the beach and was in for a mega nasty shock when the tide later came in and swept him up!
