I am pretty sure that there's one "Maiden Voyage" US CD out there with the Japanese master tape because the US master is pretty beat. I am also pretty sure that both of the "needle drop" masters, "The Jody Grind" and "Sweet Honey Bee", had the Japanese masters pulled to see if they were any better (I don't think they were) and they were probably used on their US CD as well.
Hmm, the US RVG of "Maiden Voyage" uses the Japanese master perhaps?
