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 they had 30 chart singles, 29 in the Top 40, 13 Top 10, and 4 at No. 1 between 1957 and 1984. They had 12 Top 40 albums between 1960 and 2009. The Everly Brothers were among the first 10 artists inducted into the Rock and Roll Hall of Fame in 1986. They were introduced by Neil Young, who observed that every musical group he had ever belonged to had tried, and failed, to copy the Everly Brothers' harmonies. On July 5, 1986, the Everlys returned to Shenandoah, Iowa, for a concert, parade, street dedication, class reunion, and other activities.
