I will start with Midnight Rider. My favorite version has always been the one from Gregg Allman's solo LP. But whilst looking for it, I found this amazing live version of it by Kenny Wayne Shepherd. I have seen him live. He has so much energy and charisma, the whole venue felt as if it would take off for the stratosphere.
