Don't kill me...I've been putting together a few ukulele books [I have a few uke students, and have been appalled at the lack of quality repertoire] and have arranged 20 pieces fromBriggs' book. Here is a link to the sound files from the book. I use a regular uke for most things, but for the Briggs I used a banjo-uke - not normally my fvourite instrument, but I think it sounds OK with this repertoire.

At worst you will hunt me down and kill me. At best, you might think 'Hey, that's not so bad, and it might bring one or two people our way'...
