It seems the Birmingham and the Swansea date are listed for the same day, although I suspect the Swansea one to be correct. Just seen this update from the Alexandra Theatre in Birmingham:
Chuck Berry Cancellation
Posted: 05 January 2010
Further to the postponement of the Chuck Berry concert, we can now confirm that we are unable to re-arrange a new date for the concert.
Patrons will be informed by their ticket provider and automatically refunded. Patrons should contact their ticket provider if they do not hear from them in due course.
I see those dates we're also cancelled
