I was just working out Boozoo's "keep your dress tail down" and I think it's the same fingering as Pine Grove, more or less.
I had to use Amazing Slow Downer to change the key so I could work it out on my C box(the only one with me for the winter months until I get back home and start gigging again).
I think Boozoo must have used the A key. I just bumped the pitch up.
I do play Pine Grove and it does get easier with time. After a while you'll get to where you can jam/innovate with it.
