The band known as Yes, would be an excellent addition to Bonnaroo. They can jam like no other. Their songs are classics and the musicianship is top notch. How about bringing an orchestra to go with them. Talk about giving people something to talk about. This would be an awesome experience for all involved.
I saw them with the new singer back in late 08... they were pretty awesome. New guy had some flubs here and there (at that register, who wouldn't really?), and they had to slow down some of their crazier songs, but the show through and through was a blast... if I still attended Bonnaroo, I would love to see them in a tent set late afternoon.
