As bad as you people say it is (I don't have the patience, and my comps slow), but the thing is, he is a fan of U2.
If there is a bright side to this, at least he's exposing people to U2, who might otherwise have not been exposed to their music.
Person #1 asks at Clay Aikin's tour "What's the song he's singing?"
someone who tells the person--"It's a cover by a band, called, U2",
Person #1--"hmm, wonder what the original sounds like." "Wow, this song is amazing, wonder what their other songs sound like...this band is cool!."
Hey you never know, heck I got into U2 because I was fan of actor who liked them, and curiousity took over, checked them out, and here I am writng posts on a message board about U2.
Besides, as Bob Dylan said, "your (U2's) songs are gonna last forever, but no one's going to know how to play them."
U2 really is an original of the species.
