Maybe Crocks will announce a second O2 date soon…
The O2 date seems to be (in case the RAH is announced again) more a substitute of the South England concerts (Cardiff, Brighton, Bournemouth) than the venue for London by itself... since there are concerts at the O2, there are not concerts in the South of england, but there are plenty of them in the North (Newcastle, Birmingham, Manchester, Leeds, Sheffield in last tour...)
It's like, hey, don't set up concerts in the South so if they want to see MK, they will have to travel to London to the O2, and we would fill it not only with Londoners but with people from the South that are not having concerts...
Quite an strategy.
