Mr A ???
I don't know about the motivation for the Staithes Festival..
I have been to previous events there and they always seemed a real nice bunch of people..the beer was excellent and the music and laughs were excellent...

The Roxby festival promises to be the same...Met the landlords son very nice to us..helpful etc.. the venue looked very good ,not the Albert hall but that's not what we were looking for...set in lovely country side area some nice views etc...very convenient camping ..with basic amenities..not the Ritz of campsites by any means but so close to the source of music and inebriation that even I probably wont get lost..
good sized area for beer garden..inside of the pub looked great too.

I cant answer to the motivation of any one else at either event all i know is that for £25 it looks like a no brainer to me with only the weather to be wary of.
