an early "Samba Lando" video (probably Italy)

Inti Illimani, in this staged video, dress in their youthful uniform of red ponchos. The first verse is sung by José Seves and Max Berrú. The second verse is sung by Marcelo Coulon and Horacio Salinas. The third pair in the video are Jorge Coulon, singing solo at one point, and Horacio Durán.   

They look so terribly young.
