Grease is a musical that celebrates the changes born of the late 1950s era of rock n’ roll, drive-in movies, and James Dean–an era that sat on the cusp of the turbulent 1960s. Riverside Center for the Performing Arts served up a Broadway-quality show, thanks to Director and Choreographer Patti D’Beck (who assistant choreographed Tommy Tune’s1994 Broadway revival), music, lyrics, and book by Warren Casey and Jim Jacobs, and additional songs by John Farrar. This production offers a nostalgic afternoon for music lovers of all ages that strikes like “Greased Lightning.”
