I thought Reach Out was Carol Kaye.
Love The Smithereens too Mark!
I could be wrong. It's been known to happen. HOWEVER...I did find this on
http://www.bassland.net/jamerson.html:
1) The songwriting-production team of Holland-Dozier-Holland attested to the fact that James Jamerson played on almost every one of their productions, and they never allowed others to produce songs that they had written. Brian Holland signed a notarized affidavit categorically stating that "Bernadette", "Reach Out", "Can't Help Myself", "Keep Me Hanging On", "Standing in the Shadows of Love", "Reflections", "Baby Love", "Back In My Arms Again", "Come See About Me", and "Can't Hurry Love", (all tunes claimed by Carol) were in fact, played by James Jamerson. Most damning was his statement that he had never even heard of Carol Kaye.
I think Carol also thought she played it.
Current stuff? As soon as YouTube is back online, I'll find something.
