Interesting. I didn't know that this song is from the 30's. I've only knew the version from Kusturica's No Smoking Band, or the melody from the legendary Bosnian band Zabranjeno Pusenje.
I'm honetsly not sure how old that song is and I can't find much information on the internet. It's hard to tell sometimes. "Maki Maki" by Goran Bregovic is a pretty old song called Bun e vinul ghiurghiuliu apparently. But honestly I don't really care if they are genuine folk songs or just songs written in the same style. Balkan Folk is the best! I had a blast when the Lemon Bucket Orchestra came to my town and played a mix of Balkan songs and Satisfaction outside until the police came over. Here's the video my friend took:http://www.youtube.com/watch?v=JwQJC8Oh_Ug (They played Mesecina right after the end of the video)
