Dragapella act Kinsey Sicks do a topical number about spills and drill baby drill (no it’s not that kind of video!).
I especially like the bit at the end that:
‘If you think the problem is just Goldman Sachs or BP,
there’s a walrus I can sell you in the Carribean Sea!’
because it’s easy to blame/bankrupt one corporate, when they are all, and indeed ourselves, to blame.
