Actually, some friends of mine do organise their own annual summer festival - in the back garden of one of their houses in Sussex. It's an "invitation only" festival to locals, friends and various musicians - and around 150 people turn up, with around 20 acts performing. There's a beer area, food area, proper PA and mixer system (I was doing the mix this year) - and you puts your name on the blackboard and then you performs.

It's a wonderful event. Everyone brings some food and drink, and a chair/cushion if need be. A rota of voluneers does food, drink and washing-up service. We end with a short ceilidh - after the folk, traditional ,blues, jazz, rock of the day - and then chill out around a large bonfire after 9pm.

And it's free - people just bring their music and their food/drink contribution. Performers range from 4-year olds to 84-year olds!
