Will U2 go on forever? Their fans would like to think so, but Bono says it wouldn’t necessarily be a surprise if one of the four bandmates, together for more than 40 years, wanted to call it a day at some point.

“It’s never been a given between the four of us that this would go on forever. U2 is a fast car. It’s not meant to be cruising,” Bono told the current issue of Q magazine in the U.K.

“It’s perfectly sensible for people to say, ‘Y’know what? I can’t give it anymore. I can’t stay at this level. I need some time with my kids or my friends.’ I could not hold that against anyone or myself.”

Is that time coming soon?  Nah. U2 recently finished touring the U.S. to packed houses, and they’ll hit the road again in Europe at the end of this month.

“Everyone’s been playing out of their skins and it’s been a lot of fun,” Edge says.
