Sadly the quad master tapes for the Focus albums are MIA according to the guy who curates their reissues over on the Hoffman forums. I suspect that when ABC/Dunhill (who distributed Sire, the label that licensed Focus in the US) and GRT (who did the Q8 duplication for them) were both almost simultaneously teetering on the bankruptcy abyss that they both eventually tumbled into that these tapes were either pilfered by people with access to the vaults or thrown away to save storage costs. Let's hope they turn up somewhere, someday.
