With the passing of Babbitt last summer I got to wondering about this. During the SitSoM movie there was a three way discussion with Jack Ashford, Nate Watts and Ralphie Armstrong in which Watts and Armstrong agreed that they had not heard any bassist play "What's Going On" (Marvin Gaye) the way that it was recorded with the sole exception of Babbitt, during the reunion concert. Everyone else was apparently playing a simplified version because the song is so hard to master. The movie was recorded ten years ago or so and I can't believe I'm the only one who was inspired by that comment. Every bass player has the one song he or she is in love with and plays all the time and this is the one song I keep coming back to, despite only being up to the first chorus after working on it on and off for two years (it didn't take me this long to learn "Darling Dear"). I'm a bit of a fanatic about it and am constantly comparing the way it was written to the way that it sounds on the released recording, as well as to the isolated track of Jamerson, in order to get it just right. For me, being able to replicate this song is like a painter being able to replicate the Mona Lisa. Has anyone else mastered it the way that it was actually recorded? Is anyone else taking the time and effort in their attempt to get it "just right"?
