A comment on the LDDB listing of the Japanese 25th Anniversary LD claims that it has a version of Fear of God that's 20 minutes longer than the U.S. LD. So does that mean the Japanese LD has the complete documentary?

LDDB also says that the 80s Japanese LD had analog mono (still not CX) - and lists it as having 3 sides instead of 2. So could that be a better source than the 1979 LD? There are three copies on Urabanchou - they ship to the States. There's two of the original pressing and one of the budget-priced 1989 reissue; they're all listed as 2 discs, and are all $25 (without the hefty charges to import to the States, of course).

Would it be worth it to import the first Japanese LD just for a non-compressed version of the mono? And would it be worth it to track down the Japanese 25th LD for the complete doc? (That version isn't listed on Urabanchou, though LDDB lists an Obi-less version for $50, and a sealed copy for $67.)
