Yes I fear so, you'll either need to buy a weekend ticket (£35 nonmembers, £30 members) or you can do an all day ticket for Saturday (£18 and £15 ditto). Both options will include workshops (as space permits) & sessions & concert(s). We have no facilities to restrict people's access to 'just sessions' once they're in.

Or you can do a 'just Saturday evening concert' for £10 (no concessions) but that isn't available until late afternoon (although I wouldn't like to give a definitive answer about what 'late' means, maybe about 4pm after the workshops have finished).

I'll keep checking this thread until late afternoon (UK time) but after that I have ridiculous amounts of things to sort out for the event and am unlikely to see a keyboard for a while.... (and maybe that's a good thing!)
