By biggest I think you mean oldest
I'd probably go if I had the opportunity. I went to see bb king a couple years before he died. I was glad to have had the chance to see him but the quality just wasn't even there. It was kind of sad reallyTrue...and the talent is definitely diminishing among that group. McCartney's voice has really lost it since he's gotten older. But I think that most people (and by most people I mean a whole bunch) will go for the experience and a chance to see these legends together for the last time. They represent an era that is slowly becoming a passing generation. Another 20 years and they're gone. This is a nostalgia event more than a concert...a walk down memory lane.
Roger Daltrey's voice is shot. That's a shame, because he had some pipes.
Neil Young never could sing on key, and Roger Waters could never sing a lick.
