Sitting outside the local Wetherspoons this evening, I was greatly annoyed by a group of lads at the next table who were talking loudly, and one youth in particular who was... singing loudly. And continuously. And spontaneously, improvising verses as he went along. He was even using a nonsense refrain between lines. I can't tell you any of what he was singing - it was all obscene & mostly quite offensive - but in formal terms this was the real thing. I had heard a singalong breaking out a couple of times at that pub - that's Spoons for you - but never anything like that. I wondered what the singer's friends were making of it; they didn't look shocked or even surprised.
Extraordinary, really. I put up with it for five minutes and then went inside.
