MO VE'LA BELLA MIA DA LA MUNTAGNA, sung by Matteo Salvatore, is on the album "Lamenti Di Mendicanti (Italian Beggar Songs)" (Harmonia Mundi, 195434, 2005).

You can also hear the song at YouTube.

The Harmonia Mundi web site says that Matteo Salvatore collected these beggars' songs in the Puglia province of Italy, so I suppose they are in one of the local dialects. The title does not seem to be in standard Italian.

That's all the information I was able to find.
