A good sounding transfer of the "One Fine Morning" original Lighthouse single can be had on Have a Nice Day, Volume 6 CD on Rhino:

It was NOT included on the 7 CD "Have a Nice Decade" box with the smiley carpeting, which I highly recommend. All KILLA, NO FILLA!
As to whether or not OFM is Quad, it doesn't surprise me that it is not. As I mentioned, Mark didn't list it. Besides the "smiley" Rhino Vol. 6, I do have a mint US Evolution cassette that I was gifted 40 years ago. I've never bothered to see if that decodes properly, due to azimuth, etc. issues.
I also tried to decode another Evolution title that I have on a mint US LP: "Enlightenment" by Dorothea Joyce (Evolution 3015). It synthesized fairly well, but didn't decode. If you like Laura Nyro, you might like this. Many of you may know Love's Lines, Angles and Rhymes, which she wrote and is included on this album. 5th Dimension released a single of it. Diana Ross also covered it on her first solo album.

Although there is a You Tube video of DJ's Love's Lines, it is NOT the 1972 version.
