Guy Berryman Coldplay singer CHRIS MARTIN arriving at a hotel in Stockholm, Sweden. An insider says: 'The Coldplay frontman never rests and he is the most active person. CHRIS doesn't sleep and he couldn't sleep any better before he got success. That's just what he's like. If you plugged him in you could power a small Scottish town with all of his energy.'.
