Puff the Magic What?

Been working on Puff the Magic Dragon on my guitar. Stumbled upon it accidentally - discovered the first three chords (C,Emi,F) just doodling around. Downloaded the whole thing from some guitar tab site. Quite easy actually - didn't have to learn any new chords. Surprised to learn it was written by PPM (really Peter or was it Paul and some other guy).

Getting fairly good at it. Was playing it on the deck a week or two ago while the kids were running around backyard. Neighbor girl walks up and asks what I'm playing. Puff the Magic Dragon, I said. Silence - she'd never heard of it.

Kids today - Sheesh.
