The guitar solo mentioned above was actually over-dubbed by Wayne Perkins. Most people still think it was Peter Tosh. Perkins was a session player for many artists and plays the lead guitar solo on Worried About You, by the Rolling Stones. He played guitar on many-many great albums from the 70's & 80's.
He actually replaced Eddie Hinton, who had replaced, Duane Allman at Muscle Shoals.
