Does it look like it's this set? 22nd August 99 - could be the one?

Not that I have it, but maybe knowing it was Solid Steel and when it was broadcast is helpful? Or you could try to find the track independently if it looks like the one?
this is the kind of request john peel used to moan about, obscure tracks he played years ago :d
