Well, naturally I don't really know much about what goes on outside of Britain except those in the US of Vegas, Atlantic City and NY.

However, when it comes to Britain, we got plenty of places where even English, Commonwealth or British title fights can get great audiences, across the country.

Sorry if I miss anyone out, but here's my list what I wrote:
London, Glasgow, Belfast, Cardiff, Manchester, Liverpool, Sheffield, Bradford, Leeds, Nottingham....and there is plenty of a grassroots fanbase across the country.
