The Anvil chorus comes from Il Trovatore (The Troubador) an opera by Giuseppe Verdi. I recall that the chorus was used many years ago as background music to a scene from a Disney wildlife film. The shot showed two rams repeatedly charging at each other and butting heads in time to the music - trying to gain favour with potential mates I guess (no strumming tho'). That, together with its name, should give you some idea of its character – quite unsuited to the use I’ve made of it!

I guess I might feel trepidation, and would certainly violently disapprove, if a *****ectomy was planned; it wouldn’t be performed on me, however! But... I thought trepanation or trephanition was applied to the skull?
