Arthur Freed and Nacio Scott Brown’s “Singin’ in the Rain” appears to have first been performed in 1928 in the stage show Hollywood Music Box Revue. Copyrighted in 1929, the song reached movie audiences in The Hollywood Revue, and was also heard in many later shows. Gene Kelly memorably sang it dancing through puddles and heavy showers in the 1952 movie of the same name, set around the time the song was first released. In 46 days, we can sing it in the public domain. #PublicDomainDayCountdown
