You don't always have to fork out hundreds of pounds for tickets with camping to see live bands at festivals. There are a range of smaller festivals that have tribute acts on the stage that put just as much effort into pleasing the crowd as the big bands.

I'll go compile a list now and edit this thread.

Well I have a couple, I've camped at a few.

Green Man Festival.

Hay On Wye Festival.

Moseley Folk festival although I'm not sure you can camp there?

Shambala

Will think of some more.
