I can't do the final chapter of
'The House at Pooh Corner' any more, when CR goes way to school, leaving Pooh behind...I had an absolutely brilliant bunch of Yr 4/5/6s a few years ago and, on the final day of the year, as the Yr 6's realised that this was it, the end, they asked for a final story, so I picked this one. Every time I looked up from the page, it was to see one of the girls sitting before me, with tears silently streaming down her face..."
But wherever they go, and whatever happens to them on the way, in that enchanted place on the top of the Forest a little boy and his bear will always be playing." 
Your post has brought tears to my eyes!
Back to Peter, I can add my recommendation for the Abbado/Sting/Spitting Image puppet DVD version - Sting gets the narration just right and the puppets add plenty of humour.
Another poster has very kindly send me a copy of that Sting animated puppet version. It's not appropriate for my young class but I quite enjoyed it. Some of the visual gags are a bit odd though! Best for people already familiar with the tale.
