The O2 is hosting a screening of Mamma Mia this weekend.
A sing-a-long version of the film will be shown on Sunday, January 24 on a specially made 100ft screen.
There are two screenings – 2:30pm and 6:30pm.
Tickets are £18 and can be bought from here, but those generous folk at the Evening Standard are doing a 2 for 1 ticket deal, which you can have a look at here (you have to sign up/register to the website in order to access this)
Fancy dress is welcomed, but optional!
