Audience members watching a production of Billy Elliot were asked to decide on whether a song anticipating Margaret Thatcher's death should be performed hours after she died.
The musical, which is set during the miners' strike, features the song Merry Christmas Maggie Thatcher, with lyrics that refer to celebrating the death of the former prime minister.

The show is proceeding as scheduled tonight.
