Highlights
Amor, vida de mi vida
O souverain (and opening remarks)
No puede ser
Granada (if you can, close your eyes and hear the voice of a young man)
En la calle donde vives (even I can translate that back into English!)
Merry Widow Waltz
Ella, in mariachi costume with accompanying mariachi band
Me llamas Rafaelillo, from El Gato Montes - the camera pans away just as it looks like get steamy...
El Rey - more mariachi
The concert lasted nearly three hours and could have lasted longer, but they had run out of material they hadrehearsed, and it was cold.
There are plenty more clips on YouTube, but these are a selection of the best I could find.
