And you loved it so much, you performed it on stage at your school musicals.
Others among you dressed up as the characters for charity days. And some of you held Grease-themed events in the office or the playground.
We are putting the spotlight on the mega film after the news that a Grease prequel could be on the way, starring the Pink Ladies.
In the meantime, see if you can spot someone you know in these local Grease flashback scenes.
