Well if your all feeling too old for festivals, check out High Voltage!
http://www.highvoltagefestival.com/
Specifically designed for old metal heads, ancient prog rockers etc. The only people older than the crowd will be the bands themselves!
Joking aside, quality line up if you are of 1970's vintage and quite likely the last opportunity to see some of the bands before they go senile/enter a nursing home/die.
Not sure if it counts as a festival because even if you attend both days you have to leave at night and come back the next day!
Highlights for Saturday likely to be Focus, Asia, Transatlantic, Gary Moore with ZZ Top headlining.
I'm only going on the Sunday to see mainly Steve Hackett, Marillion, Wishbone Ash, Uriah Heep and the mighty ELP headlining.
Canny wait!
