How do ELP/Brain Salad Surgery link to Half Man Half Biscuit 

My guess is Loki was thinking some call it godcore and, in particular, of a tour jacket with detachable sleeves, you know where every band performing were one of those tribute bands, and first up was H-E-L-P: Welcome back my friends, to the show that never ends. It goes on for at least two hours because we’ve got a brand new Moog. Remember Nigel thought he'd died and gone to hell, and then fallen through a trapdoor and landed on the planet Prog Rock. Then the applauding Ent Sec introduced the next act. Jeez! (That’s journalese) …PFM! They didn’t really play many songs, just got unnecessarily passionate about the Azzurri and how Rossi was framed, and how his subsequent hat-trick against the Brazilians was a big F-off to the authorities. “Fair enough”, Nigel thought, “but perhaps no need for the language.” After the Identical Cocteau Twins, came the final act, I Can’t Believe It’s Not Focus. Following a commendable stab at Sylvia, Helen shouted to the guitarist: “Are you knackered, man?” To which he replied: “No, I’m Jan Akkerman”.

But then I could be wrong
