Well a good smack of them are on my B-list. I figured a few years back that if something isn't playing out the way you thought it might do in Primavera you're best is to cut your losses and make for the fall back option. Other advice: I know the best will in the world will see a 3am band on Friday and want to see the gig at midday on the Saturday. You will not be able to move that morning. Best of luck!
Very True! Regarding park and bailing out of a dud band. last year I didn't make the park at all! best laid plans and all that. And one of my best moments was stumbling on Einstürzende Neubauten and discovering teh German Mark E Smith lol.
