O Fortuna (Part 2) 

O Fortuna de Carmina Burana (Part 2).
Every one expected only "O Fortuna", but they sang a lot more:
O Fortuna
Fortune plango vulnera
Ecce gratum
Tanz
Floret silva
Chramer, gip die varwe mir
Reie
In Taberna quando sumus
Stetit puella
O Fortuna
This is the concert in Mexico City, August 29, 2009
