Could it be perhaps that the CD re-issue (VMD 73319), released by Comet Records (www.cometrecords.com), did use the quad version and that on the CD the encoding is still intact? From listening to it (I have used Luceanu's SQ script) I would think so .... Please, feel free to check the attached sample.
While that is possible, a regular stereo master was also made at the same time (and probably first), so more likely it's stereo, not SQ. But of course the only way to be sure is to snag a copy and feed it through a decoder and hear what's what. Anyone willing to give it a go?
