Beethoven has died, and is buried in the local church graveyard.
A couple of days later, one of the ground staff is going past his grave and hears a funny noise. He listens for a bit but can't decide where it's coming from. A few days later he passes the grave again. This time the noise is louder and very obviously coming from Beethoven's grave. It sounds like music, but not like any he's heard before. Worried, he goes and gets the priest.
The priest listens carefully and tells groundsman not to worry it's just music playing in reverse. The groundsman looks confused and asks what the music is. The priest listens carefully and says that it's Beethoven's 6th Symphony. The groundsman then asks why it's happening.
The priest smiles and tells him that it's just Beethoven decomposing.....
