Son ar chistr ("The song of the cider" in the Breton language, "Ev Chistr ’ta Laou!" originally) is a traditional song of Brittany, whose words in Breton were written in 1929 by two teenagers. The melody became known by the interpretation of the famous Breton singer Alan Stivell in the 1970s and in 1977 by the Dutch band Bots under the name "Zeven dagen lang".
The song is still used by folk groups around the world and has been translated into many languages. Though many groups keep the popular motif, the lyrics sometimes differ completely from the original. The most famous covers are, in chronologic order:
