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 included Dire Straits guitarist Mark Knopfler, Rockpile drummer Terry Williams, and keyboard player Pete Wingfield. The track "She Means Nothing to Me," written and composed by John David Williams and featuring Cliff Richard as co-lead vocalist, was a UK Top 10 hit, and "Louise," written and composed by Ian Gomm, reached the Top 50 in 1983. The brothers' reunion concert at the Royal Albert Hall in London on September 23, 1983, which ended their ten-year-long solo careers, was initiated by Phil and Don alongside Terry Slater, with Wingfield as musical director. This concert was recorded for a live LP and
