Found the album, which is called Hurry Sundown.

But what IS the song about? Who lies in Boot Hill - if it's the dead gypsy woman, why was she buried there, I thought it was for men who "died with their boots on" (ie by gun violence). I also thought it was metaphorical, but apparently it's in, and maybe this is why, Tombstone Arizona.

Cowboy song fanciers care to explain?
