I know many folktales and songs. When I was a kid, my mother would sometimes sing songs from her childhood in North Carolina, and I was young when the folkies of the early Sixties were on the rise. At school we learned anthems, more folksongs and dances from around the world, so there are a number of obscure lyrics rattling around in my head, a number of which are quite disturbing to me.

Since I was quite young, I’ve found Polly Vonn a particularly disturbing song. You can’t tell me that dude didn’t intentionally murder his fiancé. I always figured that it was an arranged marriage and the thought of being tied to some long necked pasty faced woman with a honking voice sent my boy over the edge. Hunting at dusk is suspicious and who eats swans? The meat isn’t desirable, and by all accounts takes more prep than chitterlings to make it palatable. (Thanks to Dr. Kendra Hamilton for this information)
What about it, crime solvers? Innocent mistake or premeditated murder?

Furthermore, let’s consider Charming Billy:

Who is questioning him, and what is up with Charming Billy? That’s a pretty intense interrogation, so Billy either has some incredibly nosey neighbors, a suspicious mum, or he’s been in the pub trying to convince the fellas that he actually has left his basement without a pub stop and has been on a date with a real, live, human girl. So:
Is his intended actually far too young for him?
Is she dodging his creepiness?
Is she actually a Time Lord? (My TL thought was that given the contrasting ages, she might be different ages at each appearance as she slips in and out of their time together.)
Is she a figment of Charming Bill’s imagination?

Inquiring minds want to know. Folklorists, where are you?
