In France, the longest day of the year is also the longest night - 21 June is Fete de la Musique, France's national music day. It's a bit like St Patrick's Day but without the parade, the rain or the streetside vomiting.
Every French city, town and village has organised free outdoor musical events of all genres. Many venues also enter into the spirit and put on free shows.
Two Irish acts will play in Paris for the festival. Our recent Eurovision entrants Dervish are in concert at the Irish Cultural Centre, near the Pantheon. Alternatively, Simple Kid is on the bill at the Maroquinerie, a cosy little venue in the east of the city. We know which of those we'll be at.
The festival is now celebrated in cities across the world, and Dublin's large French community is also getting involved.
'French Music Feast' at Crawdaddy features traditional chanson francaise from Thomasi, some self-explanatory rock sounds by Mon Cote Punk and some world music sounds from Killdahype and various other DJs late into the night.
