American musician Phil Everly, one half of the Everly Brothers, has died, aged 74, in California.
His wife Patti said Everly had died of complications from lung disease, which she said was the result of a lifetime of smoking.
Phil Everly and his brother Don made up the Everly Brothers, one of the biggest pop acts of the 1950s and early 1960s.
They had a string of close-harmony hits including Wake Up Little Suzie, Cathy's Clown, Bye Bye Love, and All I Have To Do Is Dream.
The BBC reports the pair had an onstage break-up in 1973 that led to a decade-long estrangement, but Phil later told Time magazine the brothers' relationship had survived this.
