I know... lots of videos lately, but I couldn't pass this up. This is Jimmy Herring sitting in with Return to Forever on "School Days" in Atlanta last night. Jimmy is a little low in the mix at first, but they bring him up after about a minute. With Chick Corea on keys, Lenny White on drums, Stanley Clarke on bass, Jean-Luc Ponty on violin, and Frank Gambale on guitar. Here is the same tune from another angle.
