So MoFi only released it on SACD, or did they also release it on CD?
And I'd have to go back and read the liner notes for the '97 release. Pretty sure they said they used the original master tapes, and corrected the speed while remastering.

Just found this:
"For decades, musicians were aware that when playing along with side one of Kind of Blue it was necessary to retune their instruments to a slightly sharper pitch so as to be in tune with the recording. This anomaly was rectified in 1992 with the release of the gold Mastersound reissue of Kind of Blue, using the tape recorded at the correct pitch from the safety machine. The 1997 reissue went a step further, remixing the safety tape (at the correct pitch) and offered the only known alternative take of the whole session, the composition that opens with four bars of Bill Evans’ ‘Peace Piece."
