As reported by Reuters Yoko Ono is suing Premise Media and others involved in the making of Expelled for their illegal use of John Lennon's "Imagine":
"Yoko Ono, son, Sean Ono Lennon, and Julian Lennon, John Lennon's son from his first marriage, along with privately held publisher EMI Blackwood Music Inc filed suit in U.S. District Court in Manhattan seeking to bar the filmmakers and their distributors from continuing to use 'Imagine' in the movie.
They are also seeking unspecified damages."
Let's hope this is only the first of many. Justice never tasted so sweet.
