EDIT: For those who don't have the 7 minute Kong in Concert version (different from the OCR version), here's a link.I can kinda hear what you're talking about, but I just had another listen to it after hearing the original, and I may have found some more connections.
I'll use your code:
Green = Northern Hemispheres,
Red = Chekan Winter0:00 - 1:17 - Just chords, some of which may be pulled from the original. It does kinda sound familiar. Also, one of the synths (the 'stuttering' one. Dunno the proper term) sounds like it's playing around with the pizzicato melody at
0:20.
1:17 - 2:14 - Obvious use of pizzicato melodies (
0:20 - 0:24, 0:28 - 0:31) with some variations. Bells are playing it very closely to how it is in the original, cello is slower. The piano seems to be playing something else, or just the same thing with the notes rearranged.
2:14 - 3:29 - That one melody comes in. It doesn't sound
exactly like anything in the original, but it could be based on a lot of different pieces of it (
the pizzicato thing I mentioned a few times, 1:32). I think what you mentioned is far more likely though. The melody in the original and the one in the ReMix both play over the same part (once again, the pizzicato). It could even be a mix of both. It seems more inspired by the original though, as you said.
3:29 - 4:19 - The repeated chords at
1:17 - 1:24. Changes some of the supporting notes in the 4th bar of the first two blocks (but the connection is still strong), 3rd block is the same thing in a higher pitch, 4th block raises the pitch and holds the first chord for an extra bar (connection is still strong). Repeats (
3:58) with a melody on top of it which sounds like it was based heavily on
1:32, except it starts with the second note.
4:19 - end - Guitar doesn't seem to be from the original. Then it leads into the melody that we've already discussed and it plays 'til the end.
So there actually seems to be quite a bit of the source in there, you've just got to listen hard for it. And it does ignore a lot of the source as well.
