If you know about any type of music whatsoever, your band may not have happened if it wasn't for these 4 boys who America gave a welcome to come over. Gracious as always, they took America's very own music and gave it a twist of badness, sadness and soul. I don't know how many people of all ages asked me "If I saw this the other night . . ???? " Most of the tribute songs were very good - but, when McCartney hit the mic it was pretty awesome - he can still play and sing his rock-n-roll.
