Twice a year, at Christmas and in the summer term, toadstool coordinates a concert, involving the school orchestra, choir, parent's choir, various duets, etc. and worst of all the junior orchestra. On occasion, some of the music played or sung is quite good. However, normally it is rather poor.
Great things have happened in the past in school concerts, for instance Philip Wright (See Brass Philip and the liabilities will run into millions). Even greater things happen sometimes, including Telstar and other dismal failures. Common features in many concerts are untuned cellos, Rudolf, and Allegro in C.
Although you may think it is a total waste of time to come to school concerts, it is in fact a great, unmissable event, due to its amazing comedy value. However, you must be prepared to withstand very bad music indeed.
