ladies allowed to rhydian and only men aloud at the echo arena

Apparently the Echo arena box office has been fielding calls today from ladies who are keen to go to the Summer Pops concert tonight - but aren't sure they'll get in.
It appears some people have read the wording "Only Men Aloud" as a badly-spelled discriminatory instruction as opposed to being the name of one of the acts.
The all-male singing troupe, who won the BBC's Last Choir Standing contest, are sharing the bill with X -Factor runner-up Rhydian.
And Pops promoters tell me that everyone is welcome, whatever their sex!
