There's four of us. But £25 is still cheaper than £61.
Mind you, I wouldn't spend £20 on a night at the pub!
So, if well-known bands rehearse there, does that mean you get to know them and publicise your own band with them or something? I'm trying figure out how it would actually help you get bigger gigs and so on; I'm not saying that it doesn't help - it's something I'm sure I've heard elsewhere too - but I think I'm missing something here.
