When I bought the tickets, they give us a booklet that says that people cant take professional cameras (and guns, knifes, and all that sutff xDDD), but, I dont know, i think that if you are wearing a little camera they wont say nothing against that....

I dont know if they will stream the show on the internet, but, as Servero as said, TVE (channel 2 - La 2) will broadcast the show
