Why do we know so little about this grail? - Medicinal Sounds

For those unfamiliar, Radiohead performed under the name On a Friday from the mid 80s until the Itch EP (IIRC). Several demo tapes from have surfaced through the years and we've got rips of all of the OAF cassette tapes confirmed to exist, except for one: 1987's "Medicinal Sounds"

The release does not only hold different versions of songs the guys would rework over the years as On A Friday, but 10ish primitive radiohead songs that no one but assumably those in the small circle of the Oxford scene and assuredly some collectors who have not yet let it out to the public

It comes as a surprise that the RH community has successfully found their way around possession of the earliest songs of the band we know, but inspite this we're still missing just this one piece!

I don't doubt many a collector has made their attempt to get their hands on it, we might as well have known about for at least 15 years, which was when the first tape was release, but it seems as though not that many people know about it, and hey, it could be a pretty neat scavenger hunt, couldn't it?
