Because if we haven't seen it, other fans have seen it - I talked to someone who saw the Champagne Incident first hand and it was also reported in a gossip column a couple of days later, if I remember correctly; I saw Travie off his tits by early afternoon in Edinburg and at Decaydance he drank 3/4 of a litre of vodka during their set.

Joe has never been edge, to the best of my knowledge, but he's a stoner not a big drinker. I haven't seen him drunk myself, but what I was saying was that if these guys are drinking more even than Joe, that seems kind of weird.

When you've been in fandom a while, you just get into networks of communication, really.
