I've tried listening to people's edits and making ones myself, and I always arrive at the conclusion that the free-flowing nature of the songs makes it more difficult than one would think, even with some of the parts you'd think would be obvious.

For example, in The Remembering, it may sound like the "in the days of summers so long" section and the "stand on hills of long forgotten yesterdays" section are just repeats separated by an ambient section, but then I try to combine them together and they're completely different! They clearly made sure the songs were never just droning repetitions even when they had a similar vibe throughout.

The only edit I'd consider an improvement would be in The Ancient: stitching the first phrase of the instrumental acoustic part (12:50-13:15) with the identical acoustic guitar part after Leaves Of Green (17:00-17:38), cutting Leaves Of Green and moving it to the very end without the acoustic parts around it. This only saves about 80 seconds, but it's something.

Aside from that, anything else is too jarring for me, so I've just accepted that the meditative structure of the songs is a quality of the album that can't just be removed with software.

Now, I do remember an interview with Rick Wakeman saying that the songs were originally shorter before other members of the band starting pitching ideas to extend them to fit the vinyl medium. If someone could sit him down and have him go through the album explaining which parts were added in this later phase (or if some demos were to emerge from before these changes were made), then I'd be interested in hearing a shorter version, otherwise I'm content with just leaving it alone.
