This is totally off-topic in regards to my life in the Netherlands, but it is nevertheless a little musical experiment and is interesting to share :)

Not long time ago it came up in a discussion with my friends whether a song sang backwards will sound like the original if the audio file was played backwards. For some reason we chose the Hungarian folk song called 'Boci boci tarka' and tried on the spot, but it turned out that it's not that easy to figure out with a beer in your hand and a loud bar around you. So I took a few minutes here at home to figure out the melody and the lyrics and executed the experiment. So in this video I first sing the original, then I sing the lyrics and the melody backwards, and finally the backwards version has been reversed by lovely Audacity freeware.

So, YES, it works. Although the timing is a bit weird (I am making the pauses in the places I am used to make them in the original, instead of moving that around as well in front of or after the notes) but apart from that it works perfectly fine.
