At the 1979 GRAMMYs, disco icon Donna Summer took home her first GRAMMY, winning Best Female R&B Vocal Performance for "Last Dance." The glittering single, written by Paul Jabara for the film Thank God It’s Friday, became one of Summer’s signature hits.

Watch as Summer, radiant in a black and gold gown, accepts the award from Dionne Warwick and Quincy Jones, thanking Jabara for first introducing her to the song and having her first sing it in a bathroom in Puerto Rico. Over her legendary career, Summer earned 18 GRAMMY nominations and five wins. For more memorable GRAMMY Rewind moments, visit GRAMMY.com/videos.
