The man that talks during the whole first minute of the video and starts playing the "bandoneon" after 1:45 is my grandad's brother. This takes place in a train to Tigre in Argentina. This makes me very happy to see a stranger captured him in character  and I can see him in all his musical glory all the way in Puerto Rico. It  really makes me wonder what am I missing. Thank you stranger with a cam for making my day!
