While at ava><home, I found a post of a Steely Dan concert live from LA's Record Plant in 1974, broadcast on KMET radio. It was taken from the final board mix, pre-broadcast, and the poster says that it may be Quad-encoded. There's even an announcer blurb at the end thanking the Sansui people! This is of particular interest to me since I am both a Steely Dan fan and fondly remember the Mighty MET, so I d/l'd the file and burned it to CD.
Running it through my Onkyo's DPLII/Music setting did produce a good-sounding Surround experience. I don't know if it's really Quad or not, but while much of it is very studio-ambience sounding, there are some very convincing passages - especially where Fagan's keyboards emerge with authority from the rear speakers.
If this floats your boat, try it and see what you think:
