Shows in England 4-25 May 2005

I have a friend that will be in London, Bristol, Durham and York between May 4
and May 25. Starting and returning through London. Can someone pint me to a
list of shows during that time? He will be traveling by train (not wanting to
drive on the wrong side of the road) so shows that are convenient to public
transportation are preferred. He is shopping for historicals.

Thanks!

Mike
