Sorry, but that's not true, my best mate's parents live in Old Knebworth village,almost right next to the park arena, and got jack shit when they tried to complain about noise for Sonisphere and RHCP earlier this year.
Still think you could be right with the Knebworth or MK prediction, I hear stuff happening at Knebworth through contacts, so will post if I hear anything. (Although may have to be careful of course!)
