But at least some of the 1981 reissue was stereo, so were these changes put into the stereo versions in the reissue? I guess another question is how much of the 1981 reissue was mono.
And did imdb maybe just get this wrong? Because what I've heard elsewhere is just that these changes were in the mono. So was the 1981 reissue dominantly mono or were the stereo versions altered with these changes in 1981 or is this all a misunderstanding?
