Sing-A-Long 'Mamma Mia! - Mother's Day Mar 8, 2018 13:25:13 GMT Quote Select PostDeselect PostLink to PostMemberGive GiftBack to Top Post by Deleted on Mar 8, 2018 13:25:13 GMT A lot of UK & Irish Cinemas are showing the 'Sing-A-Long' version of 'Mamma Mia! on Mother's Day - Sunday March 11th.There was a full page Advert for it, in the UK's 'Daily Mirror' Newspaper, a few days ago.I'm not sure if it is being shown in any other Countries on Mother's Day.However, Mother's Day is on Sunday May 13th in most Countries.So the USA etc., will not get the 'Mamma Mia!' Sing-A-Long, in Cinemas, until May 13th.(If it is to be shown outside the UK & Ireland).
