Oh I understand that. Yet on the other side, we have some big name acts like Santana or Chicago, where after initially releasing the current albums, they went back to remix the earlier albums later in 1973, '74 and '75. Seeing as how The O'Jays were Columbia's top Soul Group, they may have gotten the same treatment - taking into consideration that virtually every other album of theirs appeared in Quad be it disc, tape or both. I just have this sneaking suspicion that there's a LOT of albums from 1972 (or, what I've sometimes called, "the truncated 31xxx series" of Columbia Quad releases) that were prepared, but by the time they came around for release, either other albums took precedence at time of manufacture or too much time had passed since the initial stereo release.
Maybe I'm clinging to a glass doorknob. But, I had always dreamed of having Edgar Winter's White Trash in Quad only for two songs.... fast forward a few years and there it was!
It was prepared but for whatever reason, never released. I'm speculating entirely, but I get the impression that Columbia wanted to start off their Quad program with the most recent album by Edgar Winter (which would've been They Only Come Out at Night) and then White Trash simply was forgotten about.
It's possible. And think on the bright side, if it WAS mixed to Quad, then you get the album on SACD and you won't have to clean up the mess when I explode.
That's a win-win if I ever heard one.
