My friends at Ananova report the following story:
The orchestra of Argentina's most famous theatre played in the middle of the road to protest about their low pay.
The Colon Theatre Orchestra gave a concert in front of Buenos Aires City Hall, reports Clarin.
As well as their low salaries, the musicians were complaining to Mayor Anibal Ibarra about their working conditions.
My guess would be that working conditions are far more an issue of contention than the salary, but perhaps musicians have different standards.
