This was an interesting list and I knew most of the stories already but Kris Kristofferson surprised me:
The country star was a Rhodes Scholar who studied literature at Oxford before joining the Army and rising to the rank of captain. Towards the end of his tour of duty, Kristofferson took a job as an English teacher at West Point, but he decided against the professorship at the last minute. Instead of heading to New York, he resigned his commission and moved to Nashville in 1965.A Captain in the Army? Almost a West Point professor instead of a songwriter / singer? Who knew?
