I think its important to listen to the original of songs while working on a current rendition. I've been strumming along on a generic version of One Way Out so I went back to Elmore James original recording on You Tube. For the era, it was a great performance.
As I was listening to Elmore James, I saw the video listed of the Allman Brothers playing it live in 1995 at their induction in the Rock & Roll Hall of Fame. Dickey Betts playing on this video is remarkable - kinda walked on Gregg's vocals around the 2:30 mark - but he burnt it up that night.
Play close attention to him playing rhythm behind Warren Haynes.
This is probably my favorite ABB song. I saw the video you posted and that's a great version. There's another version with Betts and Great Southern that's really good too.
The ABB's version is much closer to Sonny Boy Williamson's with Buddy Guy on guitar than to Elmore James's original. All 3 versions have their merits and it is good to go back to the original to see how a song evolves. Check out Sonny Boy's version:
