The most scary thing about the whole Vines kicked off Leno incident is the little quote from the man, reported here:
Jay Leno works in showbusiness. He's interviewed countless dozens of drug addicts, boozers, wifebeaters and auto-erotic self-flagellators. And he's tutting over a rock band being drunk in the evening? Jesus, lets hope he hasn't got Winona Ryder booked this side of the Betty Ford clinic.
(Apparently Craig Nicholls and chums had a massive fight and hit each other a bit and Leno had them escorted from the studio).
