PEARL JAM star Eddie Vedder refuses to perform live without a bottle of his friend's potent red wine by his side. The ALIVE singer has discovered the homemade tipple is the perfect onstage drink - as long as he sips it slowly. Vedder explains, "I can't do without it now. "On the first leg of our last tour, I had been drinking regular wine, but I got the good stuff for our last show, and I don't know what kind of grapes they are but it's twice as potent. "I realised this about halfway through the show. It was a political fundraiser, so I was like, 'Damn, I've really got to sober up.'"
