On this day in 1957 — after a show at the Pan Pacific Auditorium in Los Angeles — local police told Elvis Presley that he was not allowed to wiggle his hips onstage.
The local press ran headlines saying Elvis would have to clean up his act.
The next night, the Los Angeles Vice Squad filmed Elvis entire concert to study his performance.
Here, Elvis performs live on the Dorsey Brothers' Stage Show at a CBS studio in New York a year earlier.
