Radiohead guitarist Ed O Brien had a decidedly un-rock 'n' roll bachelor party - he took friends camping. The British rocker invited pals Thom Yorke, The Chemical Brothers and The Smiths' Johnny Marr on his trek into the wilderness of Dartmoor, west England, in celebration of his upcoming nuptials to long-term girlfriend Susan Cobrin. A source tells British newspaper The Sun, "The whole crew went off hiking, had campfires, played campfire songs, and generally got wasted."
