Son ar chistr
"Son ar chistr" (lit.β'Song of cider', also called "Ev chistr βta Laou!", lit.β'Drink cider, Laou!') is a traditional song of Brittany, whose words in Breton were written in 1929 by two Morbihan teenagers Jean Bernard and Jean-Marie Prima. The melody was brought to prominence through a 1970 interpretation by Breton singer and harpist Alan Stivell, and also in 1976 by the Dutch band Bots under the name "Zeven dagen lang".
