"%22Opus 17 (Don't You Worry 'bout Me)%22 is a song composed by Sandy Linzer and Denny Randell and recorded by The Four Seasons in 1966 for their album Working My Way Back to You. The song was released as the official followup to the title song of the album and reached the #13 position on the Billboard Hot 100 singles chart.This was the first hit with new full-time bassist/bass vocalist Joe Long.The title was the result of being the 17th single released by the Four Seasons.As was the case with another Linzer-Randell contribution to the Four Seasons catalog, %22Let's Hang On!%22, %22Opus 17%22 features a rhythmic vocal hook within each verse, but, unlike in most Four Seasons singles, falsetto singing is muted. except in the Coda section by Frankie Valli.This song ties Bobby Darin's %22Mack The Knife%22 for the most chromatic key changes in a rock or pop song. The song starts in the key of F# and modulates five times until reaching its ending key of B." . "false"^^ . "english" . "eng" . "false"^^ . . "Sandy Linzer" . "false"^^ . "Philips Records" .
