Some folks made a movie, a documentary, and they got sued for using 15 seconds of the John Lennon song "Imagine" without permission. The case
is Lennon v. Premise Media. That's Lennon as in Yoko Ono Lennon, joined by John's two sons and EMI Records. EMI sued in state court, and the Lennons
in federal, both for copyright infringement and they threw in some trademark infringement claims too. I think that was mainly insurance, though.
Lawyers do that. And there was a dispute as to who had the right to the copyrights.
