There is a motown song called I want you back sung by the Jackson Five. Have you heard the bass on that song and who played it. Was it James Jamerson? It really has a smokin' bass line. It gets better and better as the song goes on. He had really great chops. I wonder if it was James Jamerson. It was near the ending of the Detroit Motown era. I think they moved to LA in 72 or 73.
