It's a post accident Jan Berry piece . . . basically an alternate version of "Blow Up Music" . . . early '70s.
Thanks for the response Mark. I finally managed to track the song down, and I have to say I think its genius. While it is, as you say, a version of "Blow Up", it has become a quite different song. The lyrics - which I can't always quite make out - are brilliant comedic-satire, while the track is somehow reminiscent of the late '60s Kinks. Do you know any more detail about the track? I'm guessing its not Jan singing lead?
Cheers.
