I am always amazed by his music.
This one comes from his iconic, Songs in the key of life album.
Released in 1975. I remember this one because we would listen to this as we detassled corn that summer of 75.
Detassling corn, means you ride in a huge machine, that has arms with baskets hanging off of the arms (ever wonder why corn-rows are a certain distance apart? it so the basket for the detassler fits through!).
This album was blaring from the speakers that were next to the driver.
