I thought this was going to be about vacations to Brazil and such. Why do you say it’s gotten a surge of popularity? I’ve never heard it and listening to 10 seconds of it made me want to turn it off. So as to why there’s more versions on YouTube now, I couldn’t say.
It’s the YouTube popularity that I refer to. The cello group and solo piano versions really surprised me and the only other version I saw a year ago, other than the movie excerpt, was a vocal group imitating the soundtrack in a concert setting. http://www.youtube.com/watch?v=A9eF9FkpJWA to be precise. Rather pitiful!
I would suspect that only fans of the movie would recognize the music and the vocalese rendition of it. So why YouTube’s bump in number of versions?
