The sky blue song will struggle today as Wembley is too big to get us all 'singing together'.
'Sky Blue Army' works well - and should be background for the full 90 minutes. 'Cmon City' and ' Stand up if you love city' will also work well (but only 2-3 times before it gets tired)
Even if the team are rubbish - it'd be great to outsing the tiny yellow army
