Revkin just sang "Liberated Carbon" at scioClimate: He's removed the references to Satan and replaced them with "someone" and "BP" (I believe)

2008: Q&A: Andrew Revkin : Columbia Journalism Review

CB: In your Chancellor speech you mentioned that one thing isn’t the same, though. You wrote a song called, “Liberated Carbon,” but recently changed some of the words?

AR: Well, folk music is a plastic and evolutionary process. Originally, it said, “Satan came along and said, ‘Hey, try lighting this.’ He opened the ground and showed us coal and oil.” And, you know, I thought a lot about that. I probably approached the song initially in the voice of your traditional, Bob Dylan rabble-rouser. And now I look back, and I think, you know, it’s not Satan; it’s normal. It’s just us.

So I changed it to, “Someone came along and said, ‘Hey, try lighting this,’” which is much more human and real. And as many of my free-market, blog-commenter friends would say, look at all the benefits that have come from burning fossil fuels. So I evolved the song. And I don’t see it as an apologist saying, “Oh yeah, that was bad.” I do think it’s correct, so I changed it. And someone can say, “Oh, Revkin, you’re caving to fossil fuels.” I don’t think I’m caving; I think it’s true. And it’s been blogged on before by climate contrarians who thought they had a big ‘gotcha’ thing.

Then Satan came along and said, 'Hey, try lighting this.'

"Satan's Black Label burns in my SUV" and "they say things are getting hotter, but hey, we've got AC".
