The song in the last video is actually quite funny, there was a young couple watching him and at this point in the song is says "you are young and in love and one day you will be old and in love with someone else". BAH HA HA... sorry but I laugh each time I watch this clip.
By the way, I Googled 'old man with banjo armenia' guess who showed up? He's famous!
NOTE: I corrected the spelling of Arayik's name to Araik. He spells it without a 'Y'.
