i was disappointed with paul mccartney. i think he could have done better. and the performance with U2 as opener, surprisingly, didnt do anything for me. then again, im not the biggest U2 fan.

comfortably numb - roger sounded exactly like he does on the record, listen to it, his verses are always in stark contrast to Gilmours very tuneful chorus, its one of the things that makes the song work so well.

david and roger have both said horrible things about eachother, its not all rogers fault. asked why he hadnt talked to Waters for over 15 years a while ago, David replied, "Rogers a prick"
among other things, general bitty batty banter between the two.

"pink floyd dont need roger any more"
i dont think this is the right observation to make. im one of the people who really like the division bell album. it was brilliant, and floyd proved they can do it without roger. But with Roger, pure magic occurs. without roger, floyd would NEVER have made the wall / dark side / animals or wish you were here - and this would have rendered them relatively unknowns.
they dont NEED roger, but it would be absolutely unbelievably amazingly nice if they could do something together again
