Here in the UK there is a big telethon charity thing every November called "Children in Need".
The host is Terry Wogan, presenter of the most listened to radio show in Britain (possibly the world?). As part of Children in Need, he always hosts a charity auction for things that "money can't buy", for example last year one of the prizes was teh chance to go and meet Led Zeppelin while they were rehearsing for their comeback gig.
On his show this morning he announced that one of the lots this year will be a guitar masterclass from MK. So get your wallets out! If previous years are anything to go by this will probably go for about
