I will be very interested to see how conert ticket sales go for them. I know if I was managing them, I would schedule low-capacity venues, so to lower expectations. (When the Chicks made their comments in 2003, their tour was already sold out and the tour refused to give refunds)
However, I understand they failed to sell out 3000-seat arenas during the Vote for Change Tour in 2004.
Good point. I still wonder how many "disenchanted" Bush followers will flip to their side.
