So ... I've just spent the past hour and a half recording, editing, then uploading two videos of William Blake's The Tyger. For reasons only known to my inner Puck, I was amused to play it on the ukulele as well as the guitar. I credit the tune to Allen Ginsberg; I heard him perform it (acompanying himself on harmonium) back in the early to mid 80s.
I'm not sure which version I prefer; I definitely sing a little differently with uke than with guitar. So, I leave it to the wisdom of the cyber crowd: Do you have a preference?
The Tyger, from Songs of Experience, by William Blake.
