My friend has downloaded and looked at the track and has the following to say:
Had a chance this morning to look at the file, and I'm afraid there's no Matrix H anywhere ??
To start with, during both files does Fluff make any mention of the Queen track being in Matrix H, only the 3 (it was normally 3) Matrix H tracks that were mentioned in the intro.
I actually remember this show, I listened/recorded to all of them, it was rare to more than one band in Quad per show unless it was a special, like the Christmas show.
But I didn't just go by that, I checked out both files and found that a) they were originally mp3, or some other destructive data compression, and b) the songs themselves appear to be in mono!
There are signs of stereo but only during Fluffs jingles. Now that is odd!!!
So it looks as though the search for the Holy Grail continues. If only i could gain access to the BBC's library to track down these (almost) lost gems.
Oh, thanks for allowing access for testing purposes.
