Thanks for the response, The one off licence is what I had been led to believe was the way in the future, and with my clean record there shouldnt be a problem. Drinks licence: for the last few years I have been granted "Ocasional Permissions" to cover the 4 days required I provide my own beer and staff in a usually unlicensed premises.
The PRS are not a problem as I see it and are just used as someone else to complain about. What is £7.50 per session, less than I personally spend on beer during the same session.
Your feelings are about the same as mine then, I should be alright. The independant non pub based festival/event is not something I have seen mentioned anywhere so I thought I would start the ball rolling. I have all the relevant licences/permissions etc for this year so here's to the future.
