Supervielle - Fandango

This song: http://www.youtube.com/watch?v=oq8wHZD-FEo

I hear "Fandango" (title of the song) in the lyrics but I can't understand any of the other lyrics

Not sure if it's a dialect of Spanish or Portuguese

I hear this one:

Che bandoneón
Hoy es noche de fandango
aquí en el barrio.

Che: it's an interjection to call someone
bandoneón: large accordeon
Hoy: today
es: (it) is
noche: night
de: of
fandango
aquí: here
en: in
el barrio: the neighbourhood

Thank you! Even provided the translation!

Now if I can only find the acoustic guitar tabs..
