Remember Fatboy Slim? His notoriously low-budget dance troupe video for "Praise You" ruled MTV in 1999, but he struggled with alcoholism in subsequent years. However, the British DJ—aka Norman Cook—has been sober for the last three years and has just marked his recovery in the best way possible: by performing at last night's closing ceremony for the 2012 London Olympics on top of a giant, glowing octopus. "I gave up drinking three years ago and I've run the Brighton Marathon," he says. "Everything you do is a lot easier to deal with when you go to bed after a show rather than party for two days"—and that includes performing in front of the whole world. Although he still continues to make music and tour, he's no longer actively on a record label, which gives him complete creative control over his work—and he seems to prefer it that way. "As you get older, you realize you don't have to do any of that stuff," he says. "My career now is buoyant, but manageable. Basically, I do what I want."
