The song that Gary Barlow and Andrew Lloyd Webber created for the Queen's Diamond Jubilee celebrations is to get its first airing on BBC Radio 2 on Friday.
Entitled Sing, the track features musicians from across the Commonwealth, the Military Wives choir - and Prince Harry on tambourine.
The Prince made his contribution - his recording debut - in Jamaica, one of four Commonwealth countries that Barlow visited while compiling the song.
