I learned much of what I know about music theory and playing the ukulele by adapting some very non-traditional (for the uke) songs to play on that instrument. Here, we have Metallica's wonderful Fade to Black arranged for the ukulele, up until the second solo, at least. I changed the key to make it more convenient to play on the ukulele. The very last riff you here is the guitar melody played in the same key, which I used as a guide.
I also adapted The Unforgiven, also by Metallica, and the famous main riff of Crazy Train by Ozzy Osbourne.
