Paul can't really sing that well nowadays......but then he's 60 years old.
He still put on a great show with his last world tour though. Howard Stern even said it was the best concert he has seen in his life.
I have the live CD from that tour and some songs he just nails like when he was young ( like "I saw her standing there") and others he chops to pieces, like "Getting Better"
Another that sounds just amazing is "Coming UP"
Musically, the band is very good....but Pauls vocals are kinda failing him.
