NOPE. Not swedish, and not traditional. The music is newly composed by Swede Roger Tallroth of the band Väsen (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-770ig9bYZYM.html), but it's a celtic-styled jig, not a swedish type of tune. And the dance is... nothing swedish nor traditional. Probably a modern choreography.
Me imagino que esos movimientos son por los fuertes temperamentos del clima sueco. Y además que era bueno para desentumirse del frío junto con los sorbetes al cuerno de hidromiel.
A note from an Icelandic folklorist. To clarify, this is a traditional Icelandic folk dance, but the song is a more modern version of the song. It's called "Á Sprengisandi" and is a old traditional song from Iceland. I recommend Árni Johsens version on Spotify, it is the closest that we sing it today. Also, the costumes worn in the video are not Icelandic, they are probably from Buenos Aires as the dancers seem to be.
This is a version by Icelandic band Ríó Tríó, it's from the 70's I think, they wear rather popular in Iceland around that time. If you want a more traditional version of the song I recommend Árni Johnsens version on Spotify, he sings it as most people do today (this is a popular kids song in Iceland).
Fun video. I like legs,,,girls' legs, Irish girls' legs. I like busty girls, too, Irish girls who happily and proudly show what they're made of...sugar and spice and everything nice. Fun video. I enjoyed replaying it.
luna sky.. For one thing, song title say "Irish Dance" and careless me quite obviously missed seeing the dancing girls being in Argentina. Sugar and spice and everything nice applies to all young girls.. I did not mean to offend you or anyone. If I did, my apology goes to all.
