Tuning - C Standard

So here's Sleeps song Dragonaut. The tab that's already on this site is in
drop C rather than C standard, which is not the way it's meant to be played,
and there are a few mistakes in it too. So I made this tab, which is better.

Spanish is fun.

 (El Riffo Uno) es como "Money" de Pink Floyd, no?

you can palm mute all of El Riffo Cuatro or not, it just depends
on what you can get to sound most like the song.
