“(We’re Gonna) Rock Around The Clock” by Bill Haley & His Comets appeared over the opening credits of the 1955 film Blackboard Jungle, starring Glenn Ford and Oscar-winning legend Sidney Poitier. Placement of the song in the social commentary about teachers in a racially charged inner city school would help catapult worldwide awareness of Bill Haley’s music and contribute to a record-breaking 25+ million copies of the song sold.
