Dark end has been a favorite of mine forever. It's a song the band has played for longer than I can remember. I also like the James Carr version better, but we have always played it very much like the Commitments version at the link below. There's something about the second rise when the horns come in and the girls bring in the full background vocals. The version Mark found is good, and the guitar licks are good, but for that song maybe just a little too much dirt. Just my opinion. By the way Gene, I use a TC Chorus pedal for the opening vibrato, or a good Fender will also do the trick.
