1980s rerecordings

What most people neglect is the 1980s rerelease(s) that used a different soundtrack by Irwin Kostal. The music has only been released as a 2.0 home release, even though I believe it was a surround track. I think Taylor’s narration was redone as well, either with new footage or audio, and I think there was 2 narrators for surround or mono showings.
