(born 1937) (I. Donald) b. 1939 (Philip) I. Donald and Philip Everly were born in Kentucky to parents who soon left the coalmining region to work in radio stations. The brothers signed to Cadence Records in 1957 when they released their biggest hit, “Bye Bye Love” (1958). Appearing at Nashville’s Grand Ol’ Opry, they brought rockabilly-influenced acoustic guitar rhythms and folklike vocal harmonies to a country stage; they were the first act to perform there using drums. Also known for “Wake Up Little Susie” (1958) and “Cathy’s Clown” (1958), the Everly Brothers influenced numerous popular performers and songwriters, including Simon and Garfunkel, the Mamas & the Papas, Crosby, Stills & Nash and the Byrds.
