Hernand'o Hideway was originally a song created for a Westend London Musical "The Pajama Game", a story about a strike in a pajama factory. But it's a cover version performed by The Johnston Brother", a very oldfashionned vocal group, who became a hit in 1954. this version with the tight castagnet arrangement and the tango feeling is creating a very funny offbeat effect that clashes with the tension of the film.
