Happy birthday to rock musician Roger Waters who turns 63 today. One of the main creative forces behind Pink Floyd, Waters wrote all the lyrics and some of the music for their album, Dark Side of the Moon (1973); the album became one of the most successful in rock history. The singer/bass player left the group in the mid-1980s, and went on to perform solo. This summer he has been performing throughout Europe and today he takes his show to the US.
