OK, so since I figured out how to play Mach 4, I've been playing it whenever I'm playing my ukuleles. So after posting Mach 3 a couple of days ago, I tried a few takes playing the whole thing. Since I don't think I've ever been able to make a video playing mistake-free ukulele, I thought a couple of the takes were passable so I uploaded one. This is without a doubt one of the most enjoyable songs I've ever played on the ukulele, and it's not really that difficult once you know how to play it (of course, if you're aiming to play exactly like Kalei, then it's pretty friggin' difficult/impossible). I find it strangely relaxing to play despite the speed it's supposed to be played.
Anyway, here it is.
