Keith,
You can't leave a ticking bomb like this without some shred of evidence or fact to substantiate your statements.
I have absolutely no idea what's going on with the band although I did see a simple statement on facebook from the group announcing his leaving. So this takes me by surprise.
Of course I wholly understand your disappointment at loosing the band in the upcoming festival. I think, however, proof first, then cry foul.
Besides, John Jowitt will probably be there, he might as well fill in, he plays for everyone else.....
Here's hoping it's not what you heard. (but I'll keep my rope in case we need to lynch someone).
