I know they are old, and I know they aren't what they once were, and I know some people questioned whether or not they were worthy, but did you hear the entire audience singing along with all of their songs?
I loved every second of it. And so did my 14-year-old son. When they launched into "Who are you" he screamed: "YEAH! They're doing my favorite song!"
And I thought Ringo's boy did nice job on the drums, too.
