Can't Take My Eyes Off You is a 1967 song written by Bob Crewe and Bob Gaudio. It was recorded and released as a single by Frankie Valli. The song was amongst his biggest hits, earning a gold record.
Robert Stanley Crewe (November 1930 – September 2014) was an American songwriter, dancer, singer, manager, and record producer. He was known for producing, and co-writing with Bob Gaudio, a string of Top 10 singles for the Four Seasons. As a songwriter, his most successful songs include Big Girls Don't Cry, Walk Like a Man and Bye, Bye, Baby (all co-written with Gaudio). He also had hit recordings with Michael Jackson, Bobby Darin, Roberta Flack, Barry Manilow, and his own Bob Crewe Generation. Born in Newark in 1930, Crewe demonstrated an early and apparent gift for both art and music. Although lacking in formal musical training, he gravitated to learning from many of the great 19th- and 20th-century classical romantic composers as well as giants of jazz and swing, including Stan Kenton, Harry James, Duke Ellington, Benny Goodman, and Tommy Dorsey.Robert John Gaudio (born November, 1942) is an American songwriter, singer, musician, and record producer, and the keyboardist and backing vocalist of the pop/rock band the Four Seasons. Gaudio wrote or co-wrote and produced the vast majority of the band's music, including hits like Sherry and December, 1963 (Oh, What a Night). Though he no longer performs with the group, Gaudio and lead singer Frankie Valli remain co-owners of the Four Seasons brand. Born in the Bronx, New York, He rose to musical fame at the age of 15 as a member of The Royal Teens. In 1958, while he and the group were promoting the single, they met Frankie Valli and his group the Four Lovers as they prepared to perform on a local television program. Wearying of touring, Gaudio left the Royal Teens soon afterward, and the group subsequently dissolved. One year after he ceased touring, Gaudio joined the Four Lovers. While commercial success was elusive, the group was kept busy with session work (with Bob Crewe as the producer), and a string of performances at night clubs and lounges. In 1960 Gaudio finally shook hands with lead singer Valli and formed the Four Seasons. As well as Sherry and December, 1963 (Oh, What a Night) Gaudio wrote a string of subsequent hits for the Seasons, including Rag Doll, Save It for Me, Bye Bye Baby and Can't Take My Eyes Off You.Crewe/Gaudio compositions and productions also became major hits for other artists, including the Tremeloes, The Osmonds, Diana Ross, Nancy Sinatra, and Peabo Bryson and the song You Don't Bring Me Flowers for Barbra Streisand and Neil Diamond.
