I agree that the performance was not very good. I think the reason for that is probably because they used SNL crew instead of Paul's regular crew or something. Because the sound as a whole was also not as full as usual, and just didn't sound right as it usually does, ya know? The vocals, both Paul's and the harmonies, were way off. I think maybe they couldn't hear themselves too well, that's what it seemed like to me. Paul looked really p*ssed off whenever a particular line he sang sounded off! And I think Paul's been working on his voice recently, and he sounded great doing Here Today on Jimmy Fallon just a few days before SNL. I don't know, I think the sound wasn't set up right that night 'cause they all had trouble singing, and not just Paul.
