Hello,
I didn't have the skills and/or the patience to tab it in a music software, but I confirm that playing the 998 prelude on the low g uke is quite straightforward; just start from a standard staff notation for guitar and play the lowest notes an octave higher. Not that difficult and very effective on the uke. Even more strangely, the intimidating Fugue that follows proves to be also quite playable on the uke — but I confess this is tough work.
Regards,
Gilles
