How would you feel if you were told that in a few weeks time you had to sing for the majority of the world's population?
That is exactly what happened to a choir of young people from Edinburgh's Broomhouse Estate.
The Big Breakthrough choir has made a video of Flower of Scotland to feature at the opening ceremony for London 2012.
BBC Scotland's Gavin Walker went to watch them film it.
