Nobody told her they'd rip off John Lennon's music like this.

Yoko Ono is suing the makers of the controversial anti-evolution documentary Expelled: No Intelligence Allowed for allegedly using the late Fab's classic "Imagine" without permission.

The suit, filed in federal court in Manhattan on behalf of Ono, and Lennon's sons Sean and Julian, claim the inclusion of the classic cut suggests the family endorses the film's Darwin dissing. They are seeking unspecified damages and a court order barring the continued use of the song in the movie.

For its part, Premise Media claims the "Imagine" segment is covered under fair-use copyright rules: "Unbiased viewers of the film will see that the 'Imagine' clip was used as part of a social commentary in the exercise of free speech and freedom of inquiry."

So much for the world living as one.
