Thanks for the link Hilary - unfortunately in my haste to post details everywhere I could think of I completely forgot to put that up (at the moment the details of the cancellation haven't been entered up, but that should be rectified by tomorrow).

Actually (unless there's been any big change which I haven't spotted) the website doesn't say you _have_ to be a member - that's never been the case. Anybody can book tickets for the Institute club, but members get a more beneficial deal. (If you're intending to come to more than three evenings it pays you to take out annual membership). As far as Friday night goes there will be no admission fee, but a "hat" will be passed around - see the other thread about this if you're interested.
