In 1951 a western swing bandleader named Bill Haley recorded a version of "Rocket 88" with his group, the Saddlemen. It is considered one of the earliest recognized rockabilly recordings. Haley and his bandmates crafted a rockabilly sound during this period as the Saddlemen. It was followed by versions of "Rock the Joint" in 1952, and original works such as "Real Rock Drive" and "Crazy Man, Crazy", the latter of which reached number 12 on the American Billboard chart in 1953.
