@JerryGarcia I saw that on social media a few weeks ago. That would have been really cool, especially if it led to either:

A. Jerry sitting in with Bob Marley & The Wailers

B. Bob Marley sitting in with Jerry or the Dead

C. Jerry & Bob Marley duo

Something tells me that Jerry Garcia and Bob Marley would have been fast friends. Natty Dread on Grateful Dead records is an interesting alternate timeline to imagine.
