Songwriter. She was an American Songwriter, who wrote songs for Glen Campbell, Ricky Nelson, Brenda Lee, and Sheeley's former fiancé, Eddie Cochran. She attended Newport Harbor High School in Newport Beach, California, and briefly worked as a teen model. She went to Hollywood to meet the stars and write songs. She wrote her first song, "Poor Little Fool", which Ricky Nelson recorded in 1958, and became Nelson's first US No. 1 and the Billboard Hot 100's first No. 1. She wrote "Love Again" and "Cherished Memories" for Eddie Cochran, and the 1959 hit "Somethin' Else" with Eddie's brother Bob Cochran. Her other songwriting credits included "Hurry Up", recorded by Ritchie Valens. In April of 1960 she traveled to England to join Cochran and Gene Vincent, who were touring. She recorded a song, "Homework", with producer Jack Good. On the night of April 16, 1960, Sheeley, Vincent, and Cochran were traveling in a private hire taxi from a concert in Bristol to London airport when it blew a tire and slammed into a lamp post near Chippenham, Wiltshire. All three were rushed to a hospital. Cochran, who had been thrown from the vehicle, suffered fatal brain injuries and died the next day, at the age of 21. Sheeley suffered a broken pelvis, and Vincent broke his ribs and collarbone and added further damage to his already weak leg. Following the accident, she returned to the USA, where she collaborated with musician-songwriter Jackie DeShannon on a string of hits, including Brenda Lee's "Dum Dum" and "Heart in Hand", The Fleetwoods' "He's The Great Imposter", and Irma Thomas's "Breakaway". She also co-wrote songs with Chris Curtis of The Searchers, including "Night Time" recorded by Paul and Barry Ryan. In 1961 she married Los Angeles disc jockey Jimmy O'Neill. They created the ABC-TV series "Shindig!" from 1964 to 1966. They divorced five years later, but remained friends. After her divorce, she moved away from the music scene, apart from some public appearances at Cochran conventions in the 1990s. In August 2000, RPM Records released a collection of her songs that were recorded in the early 1960s by session musicians, including Glen Campbell, Delaney Bramlett, Leon Russell, David Gates, Hal Blaine and Herb Alpert. In 1988, Levi Strauss & Co. promoted their Levi's 501 range with a television commercial called "Eddie Cochran", directed by Syd Macartney. It told the story of how Sheeley, which played by actress Sharon Devlin, attracted Cochran at a party by wearing said product. It was seemingly narrated by Sheeley and the background song, "C'mon Everybody," was released as a promotional single, followed by a compilation album of Cochran's hits. Sheeley was depicted by Rosanna Locke in the 1987 film "La Bamba".
