Nearly seven million people went online to watch U2 live in concert yesterday (26.10.09).

The Irish band became one of the first major groups to stream an entire show live on the internet for free when they posted a video link-up to their concert at California's Pasadena Rose Bowl on YouTube.

U2 is successful because of their "mysterious" relationships. Guitarist The Edge believes the band - also consisting of frontman Bono, bassist Adam Clayton and drummer Larry Mullen Jr. - have survived almost 30 years in the music industry because they can anticipate each other's onstage antics like a rehearsed dance routine.

He said: "I'm acutely aware of what Adam, Larry and Bono are doing, whether or not we catch each other's eyes."

Bono wishes his wife wasn't so "independent." The U2 frontman fears his wife of nearly 27 years Ali Hewson doesn't need him as much as he needs her.

The 49-year-old singer said: "Our relationship has changed a lot. For a while I thought I was in charge, I was the hunter-protector."
