Beautiful job on this Kev!! You make very good use of the tools at hand. Nice clean/clear recording/mix/performance!! :)

Sounds pretty good here, but more important it comes across as a good tribute!   Just retro enough to suit, but with a modern production edge. 
 

Very smooth vocals and a nice tribute to the Hag -- a man who is generally underappreciated (imo) for his wonderful songwriting.  He often had a poetical lyrical sense (not in Okie, tho) and used chord changes which were somewhat unusual in country.  And, what a voice. I saw him perform in an intimate club here in nyc years back  -  his band was superb and so was he.  !!

Hi Kevin,
Waow pure country feel,
I've heard this songwriter was gone some days ago. I didn't know about him but he surely was a real personnality in the Nashville style music world.
Anyway ,you mastered the cover with craft.
All the best.
Olivier.
