James Taylor was born in Boston and grew up near Chapel Hill, with summers on Martha's Vineyard. His father was born in Morganton, N.C and graduated from UNC. His mother was from Newburyport MA, but the Taylors were in no way a "a very prominent Mass family." They came over from Scotland to New Bern in the 1700s. And, no, "Sweet Baby James" never wrote a song called "Goin' to Massachusetts in My Mind."
James Taylor is, was and always will be lefty no matter where he or his parents hang or hung their hats.
I am the same age as James Taylor, born and raised in North Carolina. James Taylor was a complete unknown when I was growing up in the state and he started singing and became world famous in his early 20s. Back then no one knew he had once lived in NC. Not your typical good ole boy riding around in a pickup truck drinking beer. He was the son of a prominent UNC professor. He came from money. There is nothing he has in common with the state of North Carolina, other than a few childhood memories. From the time he was a young teenager he was attending prep schools in Mass and NY. He lived in NY the majority of the 60s. I do like his song about North Carolina though.
