The Everly Brothers rock groups of the 1960s. The Beatles, The Beach Boys, and Simon & Garfunkel developed their early styles by performing Everly songs. The Bee Gees, The Hollies, The Marmalade, and other rock and roll groups that feature harmony singing were also influenced by the Everlys. The music of the Everly Brothers influenced the Beatles, who referred to themselves as "the English Everly Brothers" when Paul McCartney and John Lennon went hitchhiking south to win a talent competition. They based the vocal arrangement of "Please Please Me" on "Cathy's Clown." Keith Richards called Don Everly "one of the finest rhythm players."
The Everly Brothers Paul Simon, who worked with the pair on "Graceland," said on the day after Phil's death, "Phil and Don were the most beautiful sounding duo I ever heard. Both voices pristine and soulful. The Everlys were there at the crossroads of country and R&B. They witnessed and were part of the birth of rock and roll." The Everly Brothers had 35 Billboard Top 100 singles, 26 in the top 40. They hold the record for the most Top 100 singles by any duo and trail Hall & Oates for the most Top 40 singles by a duo.
