The theme song "St. Elmo's Fire (Man in Motion)" was written by Foster and English musician John Parr, and also performed by Parr. Foster had been impressed by Parr's song "Naughty Naughty" and invited him to perform the title track. Originally another song was chosen which Parr disliked. "That song sounded like `Fame II' or "Flashdance II," said Parr later. "I thought the movie was supposed to have more class than that. It was a regurgitated song and I didn't really want to sing it."
