Thanks everyone. Jomi, I didn't tab out the intro and, I'm embarrassed to say, during a recent purge of my inbox I must have deleted the tab for the main song by accident.
I'm not sure if Fretsource still has a copy of it?
The only thing I can help you out with is the tune I added on right at the end. It's a traditional tune usually known as Comin' thro' the rye as it is most often song with the words of that particular Burns poem. The arrangement I came up with for it is very simple (C F and G). The tab has a few timing issues but hopefully it'll be of some use to you.
