Sounded like a modern mechanical aspect of the folk process--the typo. Did this line make sense to you as you sang it (yes, I understand that "the can" is jail, etc.)? Or were you singing "he trun me" as a kind of nonsense verse? I guess the question is, does trun mean something in another language or in slang or folksong lingo?

In other words, I'm refreshing the thread. ;) Maggie
