I must retract a little bit. Ater more research I found this. Ugh!
An indie-folk rock ensemble made up of scientists already stationed in Antarctica will perform for Live Earth fulfilling Al Gore's promise for music from 7 continents on 7.7.07I don't know how verifiable the source is though. Moonbats in the Antarctic, or How to make some extra dough while stationed at McMurdo!
I've only been to Wembley Stadium once, May 7, 1972. I don't remember the vendors flogging anything but beer. If they sold food at all, it would have been one of those artery-clogging "toady holes," (a mini sausage rolled in dough, then deep fried). Mmmmmm.
BTW, that was the day of the English Football Association Cup Final. My Leeds United beat Arsenal 1-0, with Alan Clarke scoring in the 56th minute, IIRC.
