I have just seen, over on CDS, what the cause of James' injury was.
It seems James's injury involved a flagpole falling on the back of his neck/head.
So, hope that he is truly OK - and that he has seen his chyropractor (pity I won't be at Hallowedon, as I could have offered to check how bad the injury was. There will be no hugging or posing for photographs this time it seems.
I hope that everyone has a really great time.
