Howard - I've suggested that the new club tariff could be held by the club not the venue, so they can have control, and can move venues when necessary without licensing becoming an issue with the landlord. I think that's now in the scheme. (Clubs can still operate under the landlord's licence too).

PRS divides the world up into a) Concert Venues and b) Gigs And Clubs. At Concert Venues you fill in a specific 'green sheet' with your set list. PRS will add the copyright details if you leave them blank. The rest are collected under the Gigs and Clubs scheme. You won't see any paperwork because artist members send a generic set list to PRS every 50 gigs or so. But those gigs are within the PRS remit, and will appear on their system - even if the promoter is not aware of it.

Yes, it's not easy to work out who holds copyright on 'folky' material. The PRS database is a hopeless mess (as I keep telling them). You'll find 'Dirty Old Town' credited to dozens of 'writers' and 'arrangers' and you can't even prove it's Ewan's song they're talking about because there are no sound files or music sheets. (Something else I've tried to have introduced). But if you're playing tunes you probably have some responsibility to know where they came from - not least because the writer may be living (nearby?), and may not feel as most of us do about creative commons!
