When they sang “Chang chang changitty chang shoo-bop, we’ll always be together” they meant it.

On Saturday, Grease‘s Sandra Dee and Frenchy reunited for one more hand jive. Didi Conn, 63, who played Frenchy in the 1978 movie musical, surprised the audience at Olivia Newton-John’s Las Vegas show “Summer Nights” by joining Grease‘s leading gal on stage.

The two Pink Ladies treated the crowd gathered at the Flamingo Hotel & Casino to a Danny Zuko-less version of the song “Summer Nights,” reports Huffington Post. Newton-John, 66, donned her classic leather jacket during the number, while Conn opted to slip into her trademark Pink Ladies one later on.

Decades after graduating from Rydell High, the old friends are still all smiles. Newton-John and Conn spent the mini-reunion singing arm in arm and sharing several hugs.
