There is a presale on PaulMcCartney.com happening at 9 a.m. today. You've had to have been registered with the website before this morning though. I forgot to come back and post this last night. Sorry about that.
Yeah, that's most likely what that fest will be considering it's Luckyman that is promoting it. Maybe with the Uproar Festival taking over one of the three days. Had it been Stateside I would be a lot more optimistic about it.
