There's this explanation on Maartin Allcock's site:

This from Ade: "It's a weird situation. We've only been a band for a few months. We discovered, perhaps too late, that our fiddle player wasn't really the right fiddle player for us. We tried to encourage her to play the way we wanted her to, but she took umbrage and quit the band. It appears our manager/promoter was rather enamoured of her and he threw up his hands and quit the band too - cancelling the tour with only three days to go. We have rescued a couple of the gigs so far, and it looks like we may rescue a handful of other dates, but it was not possible to take over all his contracts as they stood (not least because he had the money!). But fear not, we shall rise like a Phoenix from the ashes. The two rescued gigs in Pocklington went brilliantly. We had a lot of fun. The audience had a lot of fun. This is just an annoying hiccup. The Brook in Southampton on 5th Dec is definitely back on."
