How low can they go?

as if the producers of expelled weren't bad enough in trying to equate creationism with science. now they are crying "fair use" after finding out they are being sued by yoko ono, for using her late husband john lennon's song imagine without permission. i'm curious to know. how is attempting to demonize a man (who never claimed to be a scientist) for lyrics in his song in any way pertinent to proving intelligent design to be legit science (that's the question i'm asking)? i hope she milks the filmmakers for every penny they made off this "doentary".
