Prince Harry has made his recording debut after being recruited by Gary Barlow to play on his Jubilee single.
The Prince, a keen music fan, refused to sing on the track but agreed to bash a tambourine which the Take That star recorded to use in the song.
The track, Sing, was written by Gary and Andrew Lloyd Webber and also features the chart-topping Military Wives. When it is released later this month it is expected to be the first chart single to feature a specially-recorded member of the Royal Family .
Harry added his contribution by hitting the instrument when he visited Jamaica - also one of the stopping points when Gary travelled to various Commonwealth countries to compile the song.
The musician used his laptop as a portable studio to gather recordings from locations such as Australia, Kenya and the Solomon Islands.
Gary said he became fond of Harry after meeting him a few times. "He's fun and relaxed and he's a really nice kid.
"We caught him on his last day in Jamaica. We turned up and I asked him would he play on the record and he said 'I don't sing'. But I said 'no, no - I don't want you to sing, I want you to play the tambourine'.
"Then we met him later on that night and he did the tambourine hit and we spun it into the track. He probably hasn't got a clue what he's part of just yet."
The track is credited to Gary Barlow & The Commonwealth Band, which includes 210 musicians from across the Commonwealth - one of the largest groups of musicians to appear on a UK single.
Sing will be given its first radio play on Chris Evans's breakfast show on Radio 2 and will be released by Decca Records on May 28.
