"When Bob Ford fired the ball that pulled Jesse from the wall . . . " from the ballad about Jesse James."The fall don't hurt, honey--it's when you land." from 'Scamp' by Freakwater.
[NOT FOLK but good anyway] "If I only had a dollar for every song I've sung, every time I had to play while people sat there drunk . . . " from 'Lodi' by CCR.
All of the Red Clay Ramblers' "Hot Buttered Rum". One of the only love songs I actually like.
Most of the Cowboy Junkies' "Powderfinger". I have no idea what the literal situation of that song is, but the emotions are wonderful.
