Haha! I think I know who you are now KS - you arrived early yes?
If you're referring to me - the shushing was part of the song - but it seemed to do the trick!
To be honest I don't mind folk having a chat because nights out are better if you're social but if it gets so loud it pisses off other people who want to listen to the music then the line has to be drawn. How is another question - I've seen some right rants from musicians that makes you just think 'they're tossers' (CIP: Dean Owens)...
Here is a short vid I took of MSTU (who I agree were amazing and I wish more folk were there to enjoy it) - sorry about the sound quality.

Thanks again to all at IMP & Tunnels - the coffee & soup were bloody lovely by the way. Possibly my best gig experience. I'm perhaps too easily pleased!
