Learning to play backup like the man himself will do wonders for your playing. Make sure to listen repeatedly and practice repeatedly - repeatedly. Notice how a lot of what is being played is no different than his lead. The big thing to watch out for when playing backup is that you don't play louder than the lead instrument or singer! You gotta backup and backoff while still being supportive.
