In the film "Grease", who plays Frenchy's guardian angel"?

"Grease" (1978) focuses on the lives of high school students. It is based on the 1971 musical of the same name, and it specifically focuses on the relationship of American high school student Danny Zuko and Australian vacationer Sandy Olsson. They fall in love during the summer but fear they won't see each other again.

In the film, with just a few days left until graduation from Rydell High School, Frenchy drops out to enroll in beauty school and accidentally dyes her hair pink. Her most famous scene is arguably when Frankie Avalon appears as her guardian angel and sings "Beauty School Dropout," which, paired with her pink hair, persuades her to return to Rydell. Frenchy is played by Didi Conn and is Sandy's closest friend in the Pink Ladies.

In one of this movie's well known scene, the only one left at a table in the diner is Frenchy. She removes her headscarf, revealing hot pink hair. The waitress says her head looks like an "Easter egg". Frenchy admits to the waitress that her time at beauty school is harder than she ever thought it would be. She's already dropped out of high school, now she's wishing for a guardian angel to tell her what to do. She then turns around and Frankie Avalon descends from the heavens to sing her, "Beauty school drop-out, go back to high-school". It's not a joke; he is joined by all of the Pink Ladies wearing ridiculous helmets made of towering hair rollers. To conclude this weird musical number, some of the T-Bird boys fly by like angels.
