Post concert tidy up

An annual musical event for which I had absolutely no responsibility but to turn up and enjoy myself watching my two piano pupils using their other instruments, and enjoyment of ensemble playing. 

I have been known to help with the tidying up of the music stands, but someone seems to have done a bit of work on responsibility and most people folded their own stands, to be left in the specified place prior to being packed away. 

I can claim a certain amount of credit for training my pair to tidy up after events. They know they can't chat to me after church until the tidy up jobs are done, and they automatically share the tasks out between themselves when they get to church without needing to be asked.
