It's hard to make sense of all the legal stuff, but the bottom line seems to be that the boycott was lifted after the Adams guys made a deal - and then, with the cooperation of a friendly judge they reneged on the deal, bringing the boycott back into efect.

Which I suppose provides a bit of comfort for the FA organisers, who can say they made the booking in good faith. I suppose they could argue that under the circumstances they shouldn't be expected to fulfil their contrac with Adams Mark, since it was made on a false undersatding. But, while that might be perfectly sound on moral grounds, that way they'd get into legal tangles that could end up costing more than they stand to lose if they pay up the penalty, and cancel the conference. So the only sesnible they can do is bite on the bullet, cancel, and back the boycott, and try to raise the money they stand to lose. Estimated at $1 for every thousand Americans.

Sounds in any case, whatever the (sweet) FA decide, the best music and the best people will be on the picketline. As is normally the case. (There are expections, such as the fuel protest in Britain last year...)
