On April 12, 1954, Haley with his band (now known as Bill Haley and His Comets) recorded "Rock Around the Clock" for Decca Records of New York City. When first released in May 1954, "Rock Around the Clock" made the charts for one week at number 23, and sold 75,000 copies. A year later it was featured in the film "Blackboard Jungle", and soon afterwards it was topping charts all over the world and opening up a new genre of entertainment. "Rock Around the Clock" hit No. 1, held that position for eight weeks, and was the number two song on the Billboard Hot 100 chart for 1955. The recording was, until the late 1990s, recognized by "Guinness World Records" as having the highest sales claim for a pop vinyl recording, with an "unaudited" claim of 25 million copies sold.
