The senior demographic would probably know "Alabamy Bound" which has that great lyric, "Just gave the meanest ticket man on earth all I'm worth/ To put my tootsies in a upper berth." Unfortunatly it has no refrain.

There's always "I've been working on the Railroad" and "Midnight Special" both of which have choruses. A light rail song that many might know is "Charlie and the MTA."

Have fun.
