I'd cut the Overture down to 2 main repeats of the main theme, get it done in about a minute and a half, then I'd stick the ending straight after About to Crash (Reprise), as that's the point the whole thing starts to drag. As a rough calculation, I think I could get it down to about 32 minutes. Lose Disappear and about 2 minutes off the end of Misunderstood and you're there.
