Like the medieval band of troubadors from which it is descended Tuna de Derecho of Santiago de Compostela gathers at a tavern in a little plaza after their nightly performance to continue their singing, now just for fun. The gathering finally broke up at 3:00 AM. Made up of university students, the Tuna, sings for donations to help them pay for their studies. Often racey and very suggestive, the singers are nothing if not charming. Must see in Santiago.
