wow, there's a ton of versions of this song on youtube. a lot by Nancy, and then there's covers and mashups as well. I knew it was a popular song, but had no idea I'd see that many different takes on a classic song.
this is from an appearance in Italy, and it's the best one by far- Nancy is singing live, which is a plus to some of the sillier lip-synced versions out there (that she's not surrounded by giant boots helps). I mean, really, we get that boots are in the song, but that's not really what the song is about.
