I don't know. Jack White may make sense. Guests "we can't tell you about." Maybe Jack White has a radius clause due to his Ryman shows, or a festival clause from his Hangout or Lollapalooza contract. And while he can't be on the lineup, maybe he will still show up and take the stage.
Is it intolerance if it makes you angrily uncomfortable when muslim women who wear robes and hijabs are standing around in the bathroom together in the way of the door and talking super loudly in their other language.
I have been self-employed since 1993 as a healer, coach, author, and psychic.
I see nothing wrong with booing them off the stage. Sure, they will be doing what they were booked to do, but what they do is cover another band's music. They have no artistic integrity, and thus deserve no deference.
Yeah, but why waste the time when there's other things going on? I'd rather see GZA than boo a band off stage any day
