NEW YORK (AP) — Bob Crewe, co-writer of "Can't Take My Eyes Off of You," ''Big Girls Don't Cry" and many other pop hits, has died. He was 83.

Crewe's brother, Dan Crewe, says Monday in an email that the producer, songwriter and "Jersey Boys" lyricist died Sept. 11 in Scarborough, Maine. Cause of death was unavailable.

The New Jersey-born Crewe co-wrote a number of memorable hits before helping put together The Four Seasons and meeting future collaborator Bob Gaudio. Songs written by the two helped The Four Seasons define an era in music with hits like "Walk Like a Man," ''Rag Doll," and Frankie Valli's solo hit "Can't Take My Eyes Off of You."

Crewe was inducted into the Songwriters Hall of Fame in 1992.
