Sandy and Frenchy had a mini high school reunion on Saturday night.
Years after leaving Rydale High, the fictional high school of 1978's Grease, Didi Conn, who played Frenchy, joined Olivia Newton-John onstage at the Flamingo Hotel & Casino in Las Vegas.
The duo performed "Summer Nights" as part of Newton-John's Summer Nights stage show at the casino, which also includes "Hopelessly Devoted to You" and "You're the One that I Want" from the Grease soundtrack.
Newton-John, 66, wore a black leather jacket and pants like the pair her character, Sandy, donned at the end of Grease. Conn, 66, appeared onstage later in an iconic Pink Ladies jacket.
