CHE declined because many of its campaigns succeeded - laws have been changed.
Gay life diversified. CHE's social function eclipsed permanently, probably by a raging commercial out gay metropolitan scene. Allan had and has other interests anyway - jazz, theatre, photography, public transport and keeping public conveniences open. However, during the 1990's in his home town of Bolton Allan, as a known aged homosexual, found himself approached by men in trouble - with blackmailers, having false allegations laid against them often of a frightening historic nature. That's where an accuser would claim that X years ago, when under age, he was messed about with to this degree (i.e. abused) by THIS MAN. And Allan found himself advising, befriending, watching court trials, and some on conviction have been sentenced to long periods in prison.
We also found - although the police deny this - an aggressive police policy on cottaging - particularly modern car-cruising out on the moors. And of course everything was sparked off by the Bolton Seven prosecution.
