When I was in Tunisia in June 2010 I heard a song that - as it turns out now - is very important to me and a lot depends on whether I'd be able to find it. Unfortunately the only word I remember is "bolero" (or something similarly pronounced) that was a part of the chorus, probably its beginning and a small part of the melody.
What is more, the song was probably in Spanish or Portuguese - I'm not 100% sure though, since I know neither of these languages. As far as I remember it was sang by a man or a group of artists. It was a lively song, probably some kind of disco or salsa, but again - I'm not sure as for the genre.
I can't express how much I need this song, so if you have any ideas - please help me!
