John Travolta and Olivia Newton-John star in this '70s version of the '50s. Olivia came from Australia and won the hearts of music fans. "You're The One That I Want" is the hot number here. The pair dress in black. "Tell me about it, stud!" Grease appeals to successive generations. Male/female duos perform Summer Nights to karaoke tracks. The film exaggerates. There were no T-Birds or Pink Ladies where I was from. The cast of Grease was long since out of high school, ranging in age from 19 to 35.
