On the occasion the qualification of Uruguay today to reach the round of 16 in Fifa World Cup 2010, let me share here one of the most famous pieces of music ever. It’s like the national anthem for tango, yet it’s from Uruguay and not Argentina as you’d have expected. It’s called “La Cumparsita” and was written by Gerardo Matos RodrÃguez more than 90 years ago.
