Tango's veteran couple hark back to golden age

BUENOS AIRES, Argentina - They are in their ninth decade of life, but the rhythm of tango still thrills in the legs of Oscar and Nina.

Even their competitors at last week's tango world championship conceded that this couple danced the most authentic tango of all.

Having learned tango during its golden age in 1940s Buenos Aires, Oscar Brusco and Nina Chudoba are some of the longest-surviving proponents of the art.
