On October 14, 1957, the Everly Brothers, one of the most important and influential groups in the history of rock and roll, have their first #1 song: “Wake Up Little Susie.” That success came hot on the heels of their first big hit, “Bye Bye Love,” with which they had burst onto the music scene earlier that year. Harmony singing was a part of rock and roll right from the beginning, but the three- and four-part harmonies of doo-wop, derived from black gospel and blues traditions, would never have given us Simon and Garfunkel, the Beatles or the Byrds. To get those groups, you first had to have the Everly Brothers, whose ringing, close-harmony style introduced a whole new sound into the rock-and-roll vocabulary: the sound of Appalachia set to hard-driving acoustic guitars and a subtle backbeat rhythm. “Bye Bye Love” was the first song by the Bryants to be recorded by the Everlys, establishing their trademark sound and peaking at #2 on the charts in the summer of 1957. The follow-up single, “Wake Up Little Susie,” reached the top spot on October 14, 1957, though not without stirring controversy in some parts due to lyrics that hinted at teenage sex. Literally banned in Boston at one point, the Everlys’ first chart-topper was taken at face value in most parts of the country as an insanely catchy song about two teenagers who have innocently fallen asleep at a movie only to awaken at 4:00 AM in fear of having ruined their good reputations. The Everly Brothers would earn 25 top-40 hits over the first five years of their hugely influential recording career, including two more #1s: “All I Have To Do Is Dream” (1958) and “Cathy’s Clown” (1960).
