"Last Train from Poor Valley" [Norman Blake] came out as "Last Train from Corvallis"--my dad didn't think that was a very likely setting for a sad song about a miner's wife running away.

One version I heard of "Wabash Cannonball" had a line about "ride the rods and brake-beams" and I thought it was "ride the rods and break beans", like a hobo version of breaking bread.
