This video is taken from a British series where a guy called Gareth Malone takes a group of people and turns them into a choir.
This time he's taken a group of military wives whose husbands are all in Afghanistan and turned them into a choir.
Gareth looks about 16yrs old but is actually in his mid-30s and is the Choir Master for the London Symphony Orchestra.
They wrote a song based on excerpts from letters written by the couples whilst apart and this is the beautiful result.
The single is out in the UK and thousands have been pre-ordered and all the money raised is going to military charities.
