Susan Buckner, best known to moviegoers as Grease‘s bubbly cheerleader Patty Simcox, died peacefully surrounded by loved ones in Miami on May 2.

Her death was announced by family.

Buckner’s Grease character was the Rydell High cheerleading pal of Olivia Newton-John’s Sandy. The 1978 film also starred John Travolta and Stockard Channing.

Born on January 28, 1952, in Seattle, Washington, Buckner was crowned Miss Washington in 1971 and represented the state in the Miss America pageant the following year. Soon after, she became one of The Dean Martin Show’s Golddiggers dancers, and that led her to become part of the all-girl group Fantasy and the musical duo Buckner and Pratt.

She also appeared on such variety shows as The Mac Davis Show, Sonny and Cher and, as a dancer and synchronized swimmer, The Brady Bunch Variety Hour.

In 1977, she landed her signature role of perky Patty Simcox, Grease‘s embodiment of pep and school spirit.
