Bootleg demo recording

OK, I'll admit, the subject doesn't look like it should be in the Serious Discussion, but I'm sure this is priority to fans like me who trawl around for vault stuff. Anyway, I've found a track labelled 'Innuendo Session Jam' in the torrent 'Queen - The Unreleased Tracks'. It's essentially a guitar-heavy track lasting 1:40, with Freddie exclaiming from 0:48 to 0:52 "...f**king fab! Anyway, please sing it quick, callin'..." I'm curious - it this one of the infamous 1990 tracks we all hope for and have accidentally glossed over, e.g. Assassin?

I actually created this song many many years ago. (it is me playing the piano/keyboards), the drums are by Roger, and the guitar by Brian (Innuende US promo tour sessions)...

yeah - the bit from Freddie is off the Solo Collection box set...
