U2 performed in Nashville last week and really make it special for a big fan who is blind.

Bono spotted the man who was holding up a sign that said he wanted to play a song for his wife.
"What do you want to play?" Bono said to him. "Get a guitar for this dude. Gents, we have a surprise guest." The man said he was really nervous, but once handed Bono's acoustic guitar he began playing "All I Want Is You." It started with just Bono on vocals, but soon enough the entire band joined in for a moment the man is unlikely to ever forget. When it was all done, Bono even gave him the guitar.

What a great end to a concert! What's the coolest thing you have seen at a concert?
