The most significant change you'll hear are the re-recordings from The Man Trap for season 3. The electric violin was replaced with a vocalist. This can be heard in "That Which Survives". And yes, the library versions are on this set.
Much information here. Thanks.
Wellll....just to be clear, would fight music from "The Omega Glory"
(when Kirk unties himself in the room) which seems to be a rearranged version of the Kirk v. Mitchell track from "Where No Man Has Gone Before,"
find its way on the box set?
For that matter, i'm guessing the WNMHGB fight music is included?
I recall that was not a part of GNP's TOS pilot album...huge disappointment back in the day.
