This SF band was only around for a few albums around 1970. Eddie Marshall, Mike Nock, Michael White, and Ron McClure. Ron's bass playing was wild and free. I believe he was playing a Dan Armstrong at the time.
He's playing DB on this cut, but I've heard recordings of this where he's playing electric, just awesomely. His phrasing is very much EB.
