I don't know if anybody else has seen this yet, but there is an exclusive interview on the BBC site, linked with the Culture Show. You guys who were at the filming may have seen it then (lucky people - still jealous lol!) He is drinking his orange juice, but I couldn't see any stains on his hoody, so must have been before the dipping/sucking incident
Anyhoo, here's the link - enjoy!
