It took bloomin' ages, but I finished it. It's not spaghetti western/arabic fusion, though. Sorry. Actually...
http://www.mediafire.com/file/vmtynj12ee2/RV5.mid -- this was all I had for the longest time. I never did find a middle part that fit to my satisfaction, so I never did find a way to link the last theme in with the finished product. You can hear where I tried to reference the RV3 nuetral/bird theme, and if you pay very close attention... you might hear something that sounds a bit like the Gerudo Valley theme from Ocarina of Time. XD
In the end, I decided to just stick to the four chords the whole way through. Boring, but serviceable. The song was almost going to be scrapped altogether. I couldn't link the two themes, I didn't want to draw them both out into full-fledged songs on their own, and for the past half year, I've been unable to record anything with my guitar.
When I read The End Part III, the bit where they're walking through the tunnels and dropping like flies, I realised my song fit perfectly. It didn't have to be some grand thing that encompassed the whole story - it just had to tell part of it.
http://www.mediafire.com/file/wzuejzly4tz/RV5 - The End Part III.mp3 -- I hesitate to call it finished. I'm still learning how to record my new guitars, and it turns out my main program for mixing has stopped allowing me to put plain audio files in, so I was unable to apply the right reverb and echo and all that to the live parts. So it sounds a little ... eh.
Oh, well.

Hopefully the guitar is better mixed in now.
The fake!trumpet was replaced with obviously!fake!trumpet (mellotron trumpet+trombone!) so hopefully that sounds okay too...
