“Grease” (1978): Danny (John Travolta) and Sandy (Olivia Newton-John) come from very different backgrounds, but they enjoyed a summer romance before being reunited unexpectedly at school, singing the duet “Summer Nights,” where they share very different memories about the romance quotient of what transpired between them. Of course, the complications, breakup and making up follow, but oh, those summer ni-ights.
