Every June 21st the Fête de la Musique, the Music Festival, goes on all over France. It's an anything goes, amateur/professional celebration of music where anyone who can play an instrument is encouraged to play in the streets and everyone else is invited to the party. This all got started in 1982 after one of François Mitterrand's Ministers (the political not the religious kind) came up with the idea. Maurice Fleuret was a composer, music critic and in 1981 Director of Music and Dance in the Ministry of Culture (Do we have anything like that?). He read in a government report that around 5 million people in France had been taught to play a musical instrument and, being also a music festival organizer, thought a day of free music would be cool. It's now one of the biggest events of the French summer and you can read all about it here in clumsy but at least not Google Translate English.
