Gary Barlow is on a mission to record a special song to celebrate the Queen's diamond jubilee. He writes the melody with Lord Lloyd Webber, but he wants performers from around the Commonwealth to play on it. Prince Charles gives Gary some suggestions, and Gary then embarks on an extraordinary trip, recording all manner of musicians on their home turfs to make the unique record, Sing.
