I've heard of one who's called 'Hoppy', I think he is Chris' roadie if I remember correctly. There's a funny story concerning him when the whole tour group tried to enter Canada via the US. It seems customs / immigration were suspicious he might be bringing in weed or something coz he had a pack of cigarettes and detained them at the border for three hours to conduct a thorough search, whereas a guy carrying a gun was allowed to stroll through
And last I heard, Jonny's roadie is a friend from way back... Mike or something.
This was all way back in their Parachutes & AROBTTH tours, dunno whether they're still the same ones
I got my info from one of the biographies "Look At The Stars". I think it's unofficial but all the info's pretty accurate. And yes, the roadies are a hilarious group and the band are pretty alright with them expressing their opinions e.g. when performances are somewhat off
