Were the bottom three albums you have listed here definitely released in Quad? I looked on Discogs, but couldn't find any Quad listings for those last three.
Specifically concerning "Boys and Girls", I have said it before, but I think that would be an excellent title for UMe to release as an HFPA Blu-Ray since they now own that one and it's celebrating its 30th anniversary this year (plus it's a 5.1 title as opposed to Quad)
BTO-HEAD ON ( released as a Mercury/Phonogram Q8), GRASS ROOTS 16 GREATEST (QS LP, Q8).
The ZZ TOP-FANDANGO was announced in SCHWANN as an upcoming WEA release. (A Quad mix quite possibly exsists in the vault, as SCHWANN was pretty accurate when it came to Quad reporting.)
