The Duke of Sussex has arrived at the world famous Abbey Road Studios, where Jon Bon Jovi has been recording a charity single for the royal’s Invictus Games Foundation.
Harry returned to the UK from Canada this week to begin a series of royal engagements which are likely to be his last before he steps down from royal duties on 31 March.
This year's Invictus Games in the Netherlands will be among the Duke and Duchess of Sussex's first public appearances together after they step back as senior royals, joining spectators in The Hague in May.
The Duke and Mr Bon Jovi greeted each other warmly on the steps of the world famous studio, before being ushered inside to the control room overlooking Studio 2 – where The Beatles recorded during the 1960s.
Engineer Obie O’Brien, Jon’s long-term friend and producer, was waiting to talk the prince through the process of re-recording the 2019 Bon Jovi single 'Unbroken' with the Invictus Games Choir.
Watch: Working with Harry is "something special".
The Duke of Sussex and Mr Bon Jovi followed in the footsteps of The Beatles as they recreated the Fab Four’s Abbey Road album cover during the visit.
Harry stepped on to the famous zebra crossing with the American musician and two members of the Invictus Games Choir.
On Friday afternoon, a post on the Sussex Royal Instagram page teased fans by showing Harry and Mr Bon Jovi in the studio, appearing as though they are about to sing together before the video abruptly ends.
The charity single was announced last week through a video posted on the Sussex Royal Instagram page, which showed a number of staged text messages between Harry and Mr Bon Jovi.
The song is in aid of the Invictus Games Foundation which oversees the development of the Invictus Games, the international multi-sport event for wounded, injured and sick military personnel, founded by Harry in 2014.
'Unbroken' was created by Jon Bon Jovi to shine a spotlight on veterans living with post-traumatic stress disorder and honour their service.
The musician has a close affinity with the military as both his parents served in the US Marine Corps.
He said: "I'd written the song for our military in the States, for a documentary. It was foreign to me because I hadn't served myself. Both of my parents had, my best friends all joined.
"So I took the task, and I worked very hard to make it honest and not sugar coat anything - so there are some hard lines in this song.
"But on a parallel course, and at the same time, months before anyone else had heard it, I sent it to Harry. I had been very aware of the Invictus Games and the choir, and I thought this could be something special if the soldiers would sing it and it would be a way for me to give back to the people of the UK who have given me so much love in the last 40 years.
"He said, this is a great idea, I want to participate, so we found the time."
