Thanks for the comments, always of interest to me.
Coincidentally, RT's Vincent Black Lightning was probably the first time I ever heard this tuning, too. I'm a huge RT fan and saw him perform it at a live show shortly after he had written it. I've always liked his live band line-ups, especially the current power trio, but his stuff is so raw and visceral when he does his acoustic solo shows.
I want to post a few more examples of songs in this topic to demonstrate more chord forms within the tuning. It's a fun tuning to play with and it's interesting how easily adaptable it is for different musical styles and genres.
I think "Big Yellow Taxi" might be the next thing I post. Joni obviously used this tuning for some of her songs. It's easy to find a lot of "Joni" chords within the tuning.
I'll try to include a chart of chord forms, too.
