Iranian singer Sussan Deyhim left her country in 1976 and is now based in Los Angeles.
She provides some of the vocals heard on the soundtrack for the new movie "Argo."
The film was directed by Ben Affleck and produced by George Clooney.
"Argo" is set in Tehran in 1979. Fifty-two Americans were being held hostage at the US embassy there.
Deyhim says when she read the script it "hit an emotional chord."
