Can't believe I wasn't aware of this one. If anyone ends up with a spare I'll gratefully take it off your hands.
All the venues will have been required to announce the show and put tickets on sale at the same time at the request of the promoter. All small venues guaranteed to sell out so the promoter wont have wanted any of the venues doing their own thing.It looks like it needed a tip off. I'm on the mailing lists and follow the venue and promoter on twitter but didn't get any notifications.
Perhaps Chrissie Hynde put the info out.
