Скачать или смотреть "Tuna" Music of Porto, Portugal

"Tuna" is not exclusive to Porto, it is, in fact a major school tradition all over Portugal. Primarily focused on university students who are graduating. In groups, they wander around towns and cities, performing serenades and other type of traditional music. In this instance, the students all happen to be female, but there are also male groups, as well as mixed groups of both male and female who do this traditional event. We had seen them earlier in the town of Evora, thinking it was a local tradition until we saw these performers in Porto.
When we returned home, I made it a point to look up what this was all about. Here are some links to articles that explains "Tuna" as well as other graduation ceremonies.
