Thanks very much for your comments.
For me, it was more that it appears to be a completely different piano melody, which doesn't seem to appear within the album version/mix (although, I may be wrong). The album version/mix just seems to plod along and Warren's drum track is quite uninteresting as well (and I never thought I'd admit to something like that!).
But, there are other instrumental moments that may have been edited ... Billy's Odyssey solo at the end of Flow, for example, and it would've been nice to hear an extension to Rise of just Midge's guitar with the electronic rhythm tracks ... quite sensational. Then there are the various versions of Remembering as well. So, it would be nice to hear a bonus disc of this material, but I doubt it will ever happen now.
