If you haven’t seen the parody of “This Land is Your Land,” which blasts President Bush and John Kerry with equal vigor, I have to wonder what desert island you’ve been stranded on. I’ve had at least 50 e-mails directing me to this hilarious bit of animation from JibJab Media Inc.

Ludlow Music, Inc., publsiher of the classic Woody Guthrie tune, didn’t think it was funny. They thought it infringed on their copyright and filed suit. JibJab went to the Electronic Frontier Foundation, seeking help in proving that its work fell under the “fair use” clause. The EFF’s investigation revealed that the song has actually been in the public domain since the early 1970s when Ludlow failed to renew its copyright registration.

Ludlow disputes the claim, but yesterday they dropped the suit anyway. “This Land is Your Land” now appears to belong to you and me—and JibJab. Details are in an EFF statement.

And if you were on a desert island, here’s the animation parody itself.
