U2 fans can rest easy, though: It was just a routine checkup, according to a spokeswoman for the 51-year-old singer.

Adam Bevell is a huge U2 fan. He's been to a dozen of the Irish band's concerts, and danced with his wife to U2 favorite 'All I Want Is You' during their wedding. The 32-year old father of four is also blind. At the U2 concert in Nashville, Tennessee he attended last Saturday he held up a sign advertising his services as a "blind guitar player."
