Not that I would ever bother doing that myself, but I'm sure that if you cut down the 5-song suite down to the length of a, say, 3 songs, I think it would become a concise and interesting thing to listen to in its entirety. The biggest problem (IMHO) in its current form is that Mike early on got "epic-titis", and so while TGP consumed 3 of the 12 steps, instead of maybe doing 5 for the next song (thus keeping the total number of songs maybe at 3), he actually had TDS consume only *2*. So, two songs in he wasn't even halfway through the steps.
As Mike later admitted himself in an interview, the remaining steps became a chore. He couldn't step up the pace without making it look he was trying to kill it off. And so you get an hour of what really should have been half an hour.
