The primary school headmistress was the wife of the CofE middle headmaster, but there's a limit to how complicated you can get with only 4 - 9 year olds. Listening to Radio 3 in a traffic jam on the M1 on the way north for Christmas last year I finally realised that the Czech carol that in English has the "We will rock you" chorus, is in fact musically rather nice when not sung in a wincing translation by a load of children.
