Folk song lyrics requested, please: "Begala E Vena"

One of my all-time favourite Bulgarian folk songs is "Begala E Vena" composed by Stefan Kanev.
I would love to know what the words are...the refrain seems rather simple, veno le mome yubava...but I don't speak Bulgarian well enough to make out the rest of the words. I know the words "father" and "mother" are used in there, but that's as far as I can understand.

A great version of the song is located here, on youtube:

Any help at all would be greatly appreciated.
Благодаря!

Another version can be found here:

(It's the second song they perform.)

The sound quality for this video is better, and hopefully easier for understanding what they're singing.
