It was popular - constantly one of their busiest nights according to their staff. I've still no idea why it was pulled so swiftly, but I was also told that another regular night has also been unexpectedly cancelled (I'll wait for it to be confirmed before naming it). The last time I played there, I had one of their customers trashing my equipment after he spilled in a pint into my personal CD decks/mixer. Never even got a 'sorry' from the venue. It's all a bit disappointing, to be honest.
That said, I've usually enjoyed the nights we put on there and had a great crowd.
