Song Help Request Old Greasy Coat

So, I recently started learning clawhammer on my uke. One of my goals since I started playing the ukulele has been 'Old Greasy Coat', after seeing Aaron's video on youtube. However, I can't figure out what exactly he's doing as far as chords. If anyone knew where I could find some sort of tablature or written guidance to help me in figuring it out, that'd be super awesome. I've done some searching online, and I can't seem to dig anything up on it.

Aloha Sam,
I believe that old Greasy coat is an old folk song.....and has only two chords...Am, G....I think...MM Stan...

Thanks, MM Stan! That helps me a lot; I'll try it out.

Hey Sam,
Any luck learning this song? I have been working on clawhammer style for a while now and would love to learn how to play it. I have been watching the video but there are parts I cannot figure out. I am the kind of person who learns best when I have a tab to start out with.

Aaron has the resonator uke tuned down one whole step to f Bb D G. See if that helps.
