Not sure if Mr. Sheldon got proper film credits for this songtrack.
Saw the 1964 film last week & Elmer Bernstein was credited with
the score.

What 'rocked my socks' was watching STEVE McQUEEN lip-synching
"Rockabilly" lyrics to a dewy-eyed Lee Remick character. The
mis-timing of the voice-over to the acting were worth the price of
admission.

Steve obviously made a good career move when he stopped imitating
singers & flushed out his action-packed, brooding loner, leading man screen persona.
