mystery song in mystery video

Okay,
A month or 2 ago I heard a nice little song about post peak oil at the end of a youtube video. It was in a sort of alt-folk style, and was about what we'll have to do when this happens or that happens. I can't remember the video or the song! Does this ring a bell with anyone? I would love to find it again.
Thanks for any brainstorms,
Anna

I wonder if it was this one?



Love these guys.  Like steam punk meets permaculture-core.

this is certainly not what you were thinking, but it has come to mind a lot lately.....
