At Revolver magazine’s annual Golden Gods Awards in L.A. last month, Marilyn Manson was joined by friend Johnny Depp, who busted out tasty licks on “The Beautiful People” and Eurythmics’ “Sweet Dreams.” Captain Jack also makes an appearance on Manson’s new disc, Born Villain, playing several instruments on an aggro cover of Carly Simon’s “You’re So Vain.” It turns out the pair are bros from way back: “I was on 21 Jump Street when I was 19,” Manson tells Rolling Stone. “I was an extra. If you pause the episode, you can see me running my hand through my mullet.” Note: YouTube that!
