With a hip-shaking rock ’n’ roll score featuring hits like “Summer Nights,” “Greased Lightnin’” and “We Go Together,” this beloved musical by Jim Jacobs and Warren Casey celebrates Rydell High’s class of 1959 in all their duck-tailed, bobby-soxed, gum-snapping glory.

Thursday performances are “Pay What You Will”
