The notice says proudly: 'Welcome to the Royal Albert Hall. We're back for Christmas.'

'There will be a maximum of 3,000 audience members at any one performance,' the RAH explain, 'in addition to around 100 members of front of house, security and catering staff. Our usual capacity is 5,272, staff excluded.'
So, that's 56.
