Hayley's management has now confirmed this concert and I will update the schedule accordingly.
It will feature Hayley, Raven, a male special guest and a guest school choir, and will have a similar format to the Barbican concert on 21 December 2009. Here is Karsten's summary of that concert (but the guests may be different this year).
I've gathered from Twitter that AJ Moore, Hayley's guitarist, is having some dramas getting to Glasgow. His flight was cancelled and he is now trying to get a later plane up there. Hopefully he makes it okay!
