The Stapleton on Stapleton Hall Road in north London. It was probably a bit of a dive, but we used to go there every Monday night, when we were in our early 20’s.
A great jazz/blues band called Big Chief, played every Monday. We used to drink pints of lager, eat bags of cheese and onion crisps and dance all night to the fantastic music.
We loved it. ???
I recall my sister had friends visiting and she and her partner took them to the Stapleton one night. They came back saying they had had a dreadful evening, the audience had been really rowdy, jumping around and spitting (!) and the band had been awful, they were called the Sex Pistols ...
