BrewDog pub first, but all this time later I probably still wouldn't have remembered much even if there was no beer involved.
Next on were the rather excellent Jelly.
Bubblegum Screw have been trading the toilet circuit for a few years now and are more of an out and out rock 'n' roll band than Jelly. Think New York Dolls, Stooges, and the Stones and you'll be getting the picture. The lineup of this band seems to change every time I see them, and I think the singer is the only original member left.
