Thank God they never did such humourless and boring things as later did Aphex, Orbital, Prodigy or the Orb. KLF were never boring... At least The KLF knew when to stop.

Very true. Each of the bands you list have, of course, done excellent stuff - but Aphex Twin released "Drukqs" (sp?), Orbital released "The Saint", Prodigy released "Baby's Got a Temper" (which were all shite) and the Orb - at cerain times - has seemed nothing more than a re-release machine. In my opinion anyway - maybe people disagree. The KLF's output in 1997 maybe hints at what might have happened had they trundled on in the intervening years: 2K's "**** the Millennium" bombed, not really because of the unbroadcastable "fucks", but more because the record was an uncommercial, short-term nostalgic muddled mess, brimming with too many (very old and retread) musical ideas (like the Prod's "Baby's Got a Temper" in 2002). Then we had the semi-official "Waiting for the Rights of Mu" - a mispelled titled, badly proof-read liner notes ("1980" rather than "1990" etc), the very beginning of "Waiting" cut off the soundtrack, and of course music that was already seven years old. Let's be honest, neither release boded well for any "new" KLF material, and I'm sure deep down we're all glad that what we have now is (mostly) lovingly made fan stuff, rather than badly made or artistically tired official product. Knowing when to stop is the trick. Was 1997 the sound of B&J beginning to jump the shark, I wonder?
