This is a good song. I worked on it a long time ago. I recorded it to see if it was going to work and was pretty pleased except for the part of the vocal line where I go extremely flat at the 2:31 mark. I meant to finish the tab and record a new mp3 but never got it done. I also had to tune down a full step to FA#DG in order to sing it period. My arrangement also requires a low 4th string.
Here is a link to just the first section and the original mp3 I recorded just to give you a flavor for what it might sound like on the ukulele. If you have good range to your voice maybe you can do it in standard C6 tuning.
