Bill Haley & His Comets was an American rock and roll band formed in 1947 and continuing until Haley's death in 1981. The band was also known as Bill Haley and the Comets and Bill Haley's Comets. From late 1954 to late 1956, the group recorded nine Top 20 singles, one of which was number one and three that were Top Ten. The single "Rock Around the Clock" was the best-selling rock single in the history of the genre and maintained that position for several years.
Band leader Bill Haley had previously been a Western swing performer; after recording a rockabilly version of Ike Turner and his Kings of Rhythm's "Rocket 88", one of the first rock and roll recordings, Haley changed his band's musical direction to rock music. They went on to record hit versions of "Crazy Man, Crazy", "Shake, Rattle & Roll", the aforementioned "Rock Around the Clock", "Dim, Dim the Lights", "Rock-A-Beatin' Boogie", "Razzle-Dazzle", "See You Later, Alligator", "The Saints Rock 'N' Roll" and "Rip It Up". In 1956, the group appeared in two early rock and roll movies with disc jockey Alan Freed: Rock Around the Clock and Don't Knock the Rock.
