Idk sadly about that last part
It actually depends on what platform as well, season 3 had four hour long episodes and they’re preserved that way on DVD and Prime, but Hulu has all four of them in their two part versions
Along with that the last two episodes from season 2 on Hulu are the syndicated edits and Prime/DVD have both episodes uncut
Really the only episode I know of that’s in two parts everywhere is South of the Border from season 2, other than the original NBC broadcast the only way to have the uncut version is on DVD, and that has a few song changes
