Hi!
I'm new here, just poking around... but I couldn't help but notice this thread. I just learnt Stone the Crow pretty recently.
That tab you found looks pretty terrible, if I'm honest.
What's more is I have a pretty good tab, PM me if you'd like it. I don't know that it's 100% accurate but it sounds okay, and fits in with the music well. It's a starting point at the very least.
Originally I started in DGCF, but actually worked out I could play it in DADG much easier - so that's what is tabbed out at. Based on videos I've seen, and Rex Brown's love of the drop B tuning it wouldn't surprise me if he plays it in drop B, if you're worried about playing it 'exactly' like he does.
Hope this helps. =)
