Slow-" I watched it, too. I recorded it, but I wasn't too impressed with the show. But I think you're right about Paul and Paul, though. On another thought - I think that's probably one of the reasons Led Zeppelin won't do a reunion tour. Robert Plant doesn't sing too well nowadays, either.
Madonna too! Give it up and Find Another Genre Girl!
But even tho Paul and Robert Plant's voices are not as strong, I still listen watch and listen to them, they are legendary.
