For more information on the song derived from the Spellbound score and other attempts to come up with song tie-ins to Hitchcock films (including a song written to explain the title "Vertigo" that I suspect may have inspired Mel Brooks' "High Anxiety"), you might check out the article "Sing Along with Hitch: Musically Marketing the Master of Suspense" in the Routledge anthology The Soundtrack Album: Listening to Media, edited by Paul Reinsch and Laurel Westrup.
