Neil, one of the interesting things about the Dweezil Zappa concert (performing Frank Zappa's music) which I attended was that the front two rows of the theatre were filled with jazz lecturers and students from the local music conservatorium. They had attended a pre-concert event where they could meet and talk with the musicians for a couple of hours. They were the ones clapping and cheering the loudest in the theatre. The atmosphere was electric.
