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 band mates crafted a rockabilly sound during this period as the Saddlemen. In January 1956 three new classic songs by Cash, Perkins, and Presley were released: "Folsom Prison Blues" by Cash, and "Blue Suede Shoes" by Perkins, both on Sun; and "Heartbreak Hotel" by Presley on RCA. Perkins's "Blue Suede Shoes" sold 20,000 records a day at one point, and it was the first million-selling country song to cross over to both rhythm and blues and pop charts
