Idol on Parade (1959)

Just as rock 'n' roller Jeep Jackson (Anthony Newley) reaches the top of the British music charts, the newly crowned teen idol is drafted by the British army and forced to abandon his career and begin a two-year stint in uniform.

When Jackson's scheming agent, Herbie (Sidney James), spirits the singer away from the barracks for an unauthorized recording session, the out-of-place superstar runs afoul of his ruthless superior, Sgt. Lush (William Bendix).
