It's hard to add to such a big list but my favorite is:
Billy Don't Be A Hero - Bo Donaldson & The Heywoods
A big hit in early summer 1974 when I was off to spend 'summer camp' in South Carolina.
At the time most people heard it as being about the then current Vietnam Conflict but a closer listen reveals it is actually set during the American Civil War. My sister loved to sing it for me every chance she got, LOL.

this is 'all about me' isn't it ? :D
