He may have a few wrinkles and gray hair these days, but other than that, Roger Waters of Pink Floyd still pretty much looks the same as he did when he was a schoolboy.

Waters co-founded Pink Floyd with a couple of schoolmates - Richard Wright and Nick Mason - and childhood friend Syd Barrett. When Barrett was fired due to his drug problems, Waters became the primary songwriter, which led to such masterpieces as 'The Dark Side of the Moon' before leaving in 1985.

After leaving the band he released several solo albums that continued his lyrical themes, but, in recent years, has returned to 'The Wall,' bringing it to stadiums worldwide with an elaborate stage production that emphasizes its themes. He has also been politically active, particularly in affairs regarding the Middle East.
