After watchcing that lesson video and listening to the studio cut what Jimmy Johnson is playing on the Soul Train gig is even one more variation on it. It's more of a combination of what Womack and Young played and his own take on it. That's what I love about that era. There were so many great soul players in those studios that if you listen to enough versions of studio and live cuts you find all kinds of variations. I think Motown stuff was more formulaic because it was almost always the Funk Bros. laying down the backing tracks but that Southern Soul stuff had many more players contributing. Just from watching that Muscle Shoals documentary we get some insight into some of those guys we never even realized where part of the soul and r&b hits that came out of that studio and then you had the MG's at STAX and other Memphis players like Jimmy Johnson, Reggie Young, Bobby Womack and others also playing the backing tracks. The Wrecking Crew was legendary out in LA and the Funk Bros. in Detroit but man what a wealth of stuff those guys in Memphis and Muscle Shoals produced and other than the guys who got their exposure from the Blues Bros. movies the rest remain almost nameless to anyone who isn't a musician and loved that music. And now sadly that's all gone. No one records like that any longer so where do guys go to get involved with learning to play that type of stuff woodshedding and leaning or stealing chops from one another? Thank God for all of the recordings because that's all that's keeping that stuff alive for us to enjoy and learn from.
