BLOOD
The very first pub gig I ever played was at the Salmon & Ball in the East End, a corner pub with doors onto Cambridge Heath Rd and Bethnal Green Rd. Maybe the area has been gentrified since then ... it certainly wasn't bloody gentrified when I played there.
We set up with our backs against the East wall of the pub, between the two doors, and started playing. Halfway through the first set a couple of black guys came in, bought their drinks, and sat peaceably at the back of the pub. Some of the white skinhead types at the bar were giving them the eye, and the atmosphere went thoroughly rank. It didn't help that our keyboard player was black.
Sure enough, after a while a couple of these East End good ol' boys decided to start something and headed to the back of the pub. There were some verbals, and then one of these idiots decided to do it like they do on telly and knocked the end of his beer bottle on the edge of the table = instant lethal weapon, right?
Erm ... no. I come from a family of coppers going back to Victorian times (believe it or not) and one thing I've heard plenty of is that when you smash a glass or a bottle like they do in the movies (with a prop made of sugar), the most likely outcome is that you end up with a handful of broken glass.
So tough guy idiot #1 is now standing there with blood spurting out of his hand, tough guy idiot #2 looks like he's going to cry, the two black guys seem unimpressed, and the landlord takes over. This being the heart of the old East End, the guv'nor looks exactly (and I mean exactly) like Grant from Eastenders. He drags them behind the bar so that he can run the cold tap over the damaged hand, then produces a mass of that blue kitchen towel they use in pubs and gets tough guy idiot #1 to mash it up in his hands, finally escorts them to the Cambridge Heath Road exit and shows them the way to the nearest A&E. He's done this before, hasn't he?
We're still playing.
Next, the guv'nor starts taking tables and stools and builds a barricade (seriously, I'm not making this up) against the newly-bolted door onto Cambridge Heath Road. Then he goes to the door onto Bethnal Green Road, which is actually a pair of narrow doors. He closes and bolts one of the narrow doors and takes up position in the narrow doorway that he's left open. His white t-shirt has been liberally sprayed with the blood of tough guy idiot #1 which makes him look a lot like Bruce Willis in a Die Hard movie, and there he stays for the rest of the set.
People in the pub are allowed to leave, people outside the pub are not allowed in.
Unsurprisingly, by the end of our first set the pub is empty apart from us, the guv'nor, and a barmaid. He pays us off, apologises to us (!), and we very sheepishly break down and leave.
The most astonishing thing about this story is that I ever played another gig.
