How to avoid a nightmare before Christmas?

How to Avoid a Nightmare Before Christmas?
The Park Grove Christmas Fair plans are going well and this year, it also features – The exciting Nightmare Before Christmas Disco (which we DO NOT want you to avoid of course).
There are five of us on the PTA committee. Like everyone else, we are mega busy, we have time and energy consuming jobs/businesses, some of us have a long commute to work, Christmas is also coming at us at 60 miles an hour and it already feels like it is costing 60 million pounds!
Why are we telling you this?
We physically can not organise the Christmas Fair without people chipping in to lighten the load. 
We need the following help:
On the morning of Friday 9th December – to sort stalls and wrapping items.
On the Afternoon of Friday 9th December – for Christmas Fair set up
VOLUNTEERS, VOLUNTEERS, VOLUNTEERS on the night of the 9th Dec.
Please book a slot asap on the sheet on the PTA board outside of Class 3 as this will enable us to have sweet dreams at night instead of nightmares.
