 Revival television shows and boxed CD sets such as the "Doo Wop Box" set 1–3 have rekindled interest in the music, the artists, and their stories.In December 1968, Frank Zappa's band The Mothers of Invention released a doo-wop parody/tribute album called "Cruising with Ruben & the Jets".An early notable revival of "pure" doo-wop occurred when Sha Na Na appeared at the Woodstock Festival.
