Last night I went to a concert in Symphony Hall, Birmingham. The band was the Philharmonia conducted by Riccardo Muti and the soloist Joshua Bell in an all Beethoven programme:- the Violin Concerto in the first half and Symphony number 3, Eroica, in the second.
This is one of the world champion noisiest audiences I have come across. They cough, talk, drop things, tap and hum. The music, by the way, was fantastic (when I could hear it).
Have fun with them.
