American songwriter Ellie Greenwich, whose credits include some of the most memorable pop tunes of the 1960s, has died in New York.
In collaboration with producer Phil Spector and Jeff Barry, her husband at the time, Greenwich wrote such hits as "Chapel of Love" and "Da Doo Ron Ron". She also produced some of Neil Diamond's early hits.
She was inducted into the Songwriters Hall of Fame in 1991.
Her manager says Ms Greenwich died in hospital of a heart attack. She was 68.
