Coldplay have almost had full-blown fights while on tour.
Matt McGinn - the band's roadie - explained: "Chris temporarily lost touch with his niceness and called his friend a **** in so venomous a fashion that our loveable Caledonian felt moved to respond thus, 'I'm going to f***ing hit you in a minute'. 'Well go on then!' came the retort, sounding more like an order than an invite.
"B****y hell, here we go, I thought. Guy has confessed to me since that at this point he became so furious that anything could have happened, and he really wasn't much more than a kilt's width from braining Chris with his vintage Fender."
Matt admitted while many people consider Chris to be the band's frontman, Coldplay is actually more of a democratic unit.
In his new book 'Roadie: My Life on the Road with Coldplay', he said: "Coldplay function as a unit. For a start, when push comes to shove they aren't really at all scared of one another, which cuts out the tiptoeing that a lot of groups might waste time doing.
"Plus, despite the generally held public notion that Chris is the boss, I hope you're getting a picture of a gang of lads rather than one dude and his hired help.
