Bono, the frontman of legendary Irish rock band U2, is one of the world's most famous musicians. If you had to pick one thing about his appearance that you associate him with, it would almost certainly be his famous dark sunglasses.
If you went back to the early 1980s, though, you'd find his hair equally as remarkable. Bono actually had long locks when the band started making music, and only cut his hair short when their sound became a little more punk.
