I don't think anything ever happened with it. Jarvis took the raw footage with him to London in 1988 and used bits in the Death Goes to the Disco film, but in his own words "There was no way that an "in concert" type of thing was going to work" (due to the concert being a shambles? And/or maybe some issues with the filming??) so presumably that's all that ever done with it.

If the original camera tapes still exist it'd be so cool to see some kind of edit, but I can't see much likelihood of it happening. Then again, if 30-odd years has softened Jarvis' initial horror at how the whole thing panned out...

Yes, according to Mark Webber it's the engineer's headphone mix, so it includes moments where he solos particular instruments to check the sound, etc. Whether that's the only recording I don't know - as you say, maybe/hopefully there'll be some sort of audio on the camera tapes too.

Doubt it, he doesn't give much away.

Cool! Any other details from the interview? "I am the Chilean Pulp Fan Rep and you will answer me!"

Maybe that's what we need in order to get a Jarvis Bar Italian inquest, er, interview.
