My comment was simply that it's quite a long way for me to go, so I may not be up for it, particularly as I am not mobile at the moment....
As far as I know, it is only on on a Friday, and then only fortnightly, although I am not sure about that, as I rely on my Camberwell friend to tell me about it. So you have to watch out for who is on. I have seen some brilliant bands there. The trick is to get there as early as possible, because it is a church crypt, not very big, and has lots of pillars to restrict view. I usually try and sit at the very front.
They do food - kind of healthy, home made stuff, and the only alcohol they sell is bottled beer and wine, and you are not allowed to bring your own.
But it really is good. Kind of quirky and old fashioned all at once.
Wear warm clothes if it is cold outside, though - it really doesn't heat up in there.
