This Land and Fair Use

There is an article at Wired.com about lawsuits arising from the JibJab animation called, “This Land.” The estate of Woodie Guthrie threatened a lawsuit. JibJab preemtively filed their own suit. From Bibliofuture, I think this is going to be an open and shut case. Parodies have been looked at as protected speech in most cases and “This Land” falls right into that category.
