I was browsing through this site which is a list of all the LP's released under the CBS combined numbering system (including Columbia, Epic, Philadelphia International, Blue Sky, T-Neck, etc) including quadraphonic releases, and I came across a couple of listings for quad albums I don't think were ever released. If you have a look at the page you'll see that it's very extensive in terms of info, but also very accurate...which makes me think it's quite possible these LP's were slated for release and then cancelled.
The two titles I'm referring to are:
Poco 'From The Inside' EQ-30753 (1972)
This album came between Poco's first quad release (Deliverin' 1970) and it's last 3 (Crazy Eyes (1973), Cantamos (1974), and Seven (1974)). It was engineered by Charlie Bragg (who did quad mixes for Lynn Anderson, Jim Nabors, Ray Price and Tammy Wynette in 1972) and Roy Segal (who did the quad mix of Chase's 1st album in 1972 and Sly Stone's 'High On You' in 1975). I don't think this is a particularly well known/well regarded Poco album, maybe the quad release was cancelled on that basis.
Mac Davis 'Forever Lovers' PCQ-34105 (May 1976)
Davis had 4 quad albums before this one (basically one a year starting in 1972) and one of the final quad releases ('Thunder In The Afternoon') the year after this, in 1977. Again it doesn't seem out of the realm of possibility that they did a quad mix of this at the same time as the stereo mix and then didn't bother putting it out for whatever reason - most likely because quad was in it's death throes by 1976.
Obviously these aren't blockbuster titles or anything, but it's always interesting to find another little piece of the quad puzzle as far as what record company intentions were back then.
