I was listening to the concert yesterday and to my ambarrassment I realized that in the recording you can clearly hear my three years old son talking during the first bars of Hedwig's theme. He loves the Raiders March and when it was over he went on saying "Oh , it's over". We were in 2nd row and hence near the microphones.
Hi everyone! After years reading this forum I'm finally joining in.
I attended the Madrid Concert as well. It was an incredible performance, in my opinion, even better than the September one by the same orchestra. For me the real highlight was the incredible performance of the violins in Hedwig's theme. I was in second row and could testify what a difficult task was for them to perform that piece.
By the way, the concert was broadcasted live by RNE. --Link remove, by the way I did not paste it correctly...
