lazyweb, help me!

I'm looking for a folk song of which the video was a popular link several months ago, only I don't remember the title, the band, or even what language it was in. It was European, I think Scandinavian, and it was sung by a group with a female lead, very fast, lots of consonants rattled off, k's & l's & r's trilling by. I think it was about a boy or girl, not much content when I looked up a translation. There were some videos out of other people singing it as a challenge, too. Can anyone help me out?

(I think Alex would really like it, given how much she loves Crazy Frog)
