Troubled singer/songwriter Rufus Wainwright credits classical music with saving him from a life of drug abuse.

The 32-year-old musician hails the genre as the key to his successful rehab ordeal from a crystal meth addiction, and insists it should be an inspiration to every artist, regardless of their age or lifestyle.

He says, "The greatest asset during my rehab process has been the influence of classical music, which saved my life.

"Unlike rock 'n' roll, where drugs, sex and debauchery are the norm, you can write your most interesting music when you're old, fat and ugly."
