SMW MSU-1 Patch WIP 4 - That ending music

Here's one case where the weird way SMW's music worked didn't exactly help me. Con managed to get MSU1 to play on all three parts after multiple attempts, but unfortunately the only real solid "arrange" version I could recall for this track - the one in "Nintendo Super Famicom Game Music" - needed a lot of altering to fit in, and even then I can hear a few audio gaffs due to the source material I was using. Any other suggestions - or a better audio editor - would be appreciated.
