Mike Eder describes "Roustabout" as "geeky, with abysmal lyrics and a generic backing".[4] On the other hand, the song originally intended as the title track was, in his opinion, "a respectable rocker"[4] and a surpringly "great song for the period".[3]
The Elvis Presley official website recounts:
It was only after the completion of the picture that Hal Wallis nixed the already recorded Otis Blackwell–Winfield Scott title track for what he deemed its "risqué" lyrics, but the always efficient team of Giant/Baum/Kaye jumped right in and delivered a new one. The soundtrack was better integrated than some but of no higher quality, and there was no song strong enough to be released as a single.[1]
(In fact, the song "Roustabout" was released as a promotional single.)[8][9]
