More Nintendo themes...

Following on from my earlier post, I've got three links which are all quite strange yet entertaining and they're all examples of Nintendo music being played on unusual instruments.
Firstly, there's this one which is a guy playing the Mario theme on his guitar. It's pretty impressive (he does the sound effects too!) - thanks to Ken for this.
Secondly, there's this one which is a bloke (Jean Baudin - there's a link on his website to a clip of him playing the same thing on an 11 string bass - you've never seen such a crazy guitar!!) who's playing the same theme but on his bass guitar - it's a 9 string, Pac-Man themed bass (worth watching the clip just to see that) and he plays it in a 'tapped' style that's really very clever to watch.
Finally, I've found this link which is a group of a capella singers doing a whole medley of Nintendo themes! Be patient - I found it quite slow.
Have fun!
