The website says that tickets are available on the door for most events, so you should be ok. Otherwise we could stand outside the door and give them a few "Murdered shanties and Improper sea songs"

Good on you Matthew,look forward to seeing you. I don't know of anything much more exuberant than "Hail Smiling Morn" and I think it's one that's on the list.

Yvonne says that she's comming but only to the concert - unless you can persuade her otherwise.
