Hey Q-eight
Which Bowie release was mentioned by RCA?
Also of note 2 tracks on vol 2 are from Bannatyne so it may exist in whole or in part as a Quad mix gathering dust in RCA's vault.
Actually, three songs from Bannatyne made it to the Best Of #2: Sour Suite, Rain Dance & Life in the Bloodstream. It's also the only Guess Who album to not be released in Quad - so you may be right - it may have been mixed.
I recall an article in a 1975 edition of Billboard Magazine. It didn't name either album by title, but just said look for upcoming Quad material from RCA featuring John Denver and David Bowie.
Hopefully, this link will work: https://books.google.ca/books?id=Eh...4Q6AEwAg#v=onepage&q=john denver quad&f=false
But by 1975, Poems, Prayers & Promises was a two-year old album and should've been released by then. So, that would be ruled out from the reference in the article. The David Bowie title never materialized so.... I can only assume we're talking two unreleased albums. John Denver's big one in '75 was "Rocky Mountain High" so that's what I always assumed it was. Your guess is as good as mine as to what the Bowie title was.
