From Seattle Times- Dinah Manoff, who played Pink Lady Marty Maraschino in the film, had worked with Travolta before, doing a guest spot on “Welcome Back, Kotter” in 1976.

But she told the Seattle Times that watching the actor, who was 24 and had just finished “Saturday Night Fever,” was one of the biggest thrills of the “Grease” experience.

“He was magical,” He had a power at that moment in time that was so incandescent and irresistible, sexy and charismatic … When you were around him, you felt it, like a vibration coming off him.”

She remembers, midway through the shoot, that Travolta took a group of them to see a “Saturday Night Fever” screening.

“We all sat in that movie theater with our mouths hanging open, going, ‘Oh my God, we’re witnessing a real moment here. We’re in the presence of something very big.'”

She remembered the long, long hours of the movie’s big production numbers: “Summer Nights,” “We Go Together” and the dance-at-the-gym centerpiece-which, she said, took a couple of weeks. “It’s a testament to Randal (Kleiser) the director and to Pat Birch and really to John and Olivia that everything looked so effortless, because it was grueling.”

And though she has few souvenirs from “Grease,” she treasures the memories and loves the new singalong version. “It should have always been a singalong,” she said. “I think it works best in this way, where the audience gets to be in the movie. It’s like ‘Rocky Horror’ – you want to sing when you’re watching this thing anyway!”
