[KLF] Acid Brass/ Williams Fairey Brass Band

Does anyone know if "Acid Brass", a.k.a. the Williams Fairey Brass Band, are still touring and recording? I'd presume that they wouldn't be doing the "Acid Brass" stuff any more, but does anyone know (a) if they do tours, and (b) if they've released any other records of brass band music apart from the studio and live "Acid Brass" CDs? Also, has anyone on the list actually seen them live? (I remember once reading a description of Bjork dancing down the front of one of their gigs during "WTIL"). John Not Scots, just Scott-ish
