Global Radio 30 Leicester Square London WC2H 7LA is defiantly it. I sent them two drawings I did of them, got a reply on twitter from them thanking me. And then about a month later I got a letter with their autographs. Yeah they come over to London a lot so they pick it up then, or perhaps someone takes it over for them? My letter said it was sent to me from Glasgow so :S
