On this day in music history: July 9, 1955 – “(We’re Gonna) Rock Around The Clock” by Bill Haley And His Comets hits #1 on the Billboard Best Sellers chart for 8 weeks. Recorded on April 12, 1954 at the Pythian Temple in New York City, the song goes largely unnoticed when it is initially released in May of 1954 as the B-side of the single “Thirteen Women (And Only One Man In Town)”. It is only after it is used for the opening title sequence to the film “The Blackboard Jungle” (starring Glenn Ford), nearly a year later that record finally takes off. Entering the Best Sellers chart at #22 on May 21, 1955, it climbs to the top of the chart seven weeks later. The song creates a sensation around the world, causing teenagers to riot and dance in the aisles of movie theaters. It is regarded as a landmark in music history as the first number one single of the Rock Era. The record also earns a place in the Guinness World Book Of Records for the largest selling rock and roll record of all time, with sales to be estimated at over 25 million copies sold worldwide. “(We’re Gonna) Rock Around The Clock” is certified Gold in the US by the RIAA, and is inducted into the Grammy Hall Of Fame in 1982.
