Won't you please walk my dog? I think it's only fair.

The story:

Working at a summer camp, I was on an off-duty day road trip with a friend and was delighted to find out that we'd both loved Traffic's "John Barleycorn Must Die" album for years. We sang through all the songs together and just outside Portland, Maine, we got to the chorus of the last song. I warbled the lines I knew from when I was a kid and noticed I was singing by myself. He just burst out laughing and didn't stop for ten minutes. He taunts me to this day.
