they were actual references to existing stories and ideas (the JAMM, the wickerman on jura, etc etc)

Wicker Man on Summerisle, surely! ;-) Interested to note Robert Rankin uses the "23" reference. I've read a couple of his books, although sometimes the in-jokes (if you haven't read all his works) can be a bit off-putting. I often wonder if there are similar discussions on Douglas Adams lists about the number "42"? Picked completely at random by the sci-fi satirist, of course - but it has grown to achieve larger proportions since it first appeared in his work. Anyone know what number Fox Mulder lives at in the "X-Files" ...? Oh, and of course, I was not going along in any way with Anthea Turner's description of the KLF (particularly, as has been pointed out, since Wanda Dee and Ricardo Da Force were there on stage, and Tony Thorpe was just about to release those wonderful remixes).
