The prince and the popstar greeted each other at the studio where the Beatles recorded a string of iconic albums.
Bon Jovi was re-recording his 2019 single “Unbroken’’ in aid of the foundation that oversees the sporting event founded by Harry. The song was created to shine a spotlight on veterans living with post-traumatic stress disorder.
The pair were seen in a recording booth wearing headphones. Bon Jovi had a guitar.
“We've been gargling next door, so we're ready to go,” Harry told an engineer.
The event is one of the last official engagements being undertaken by Prince Harry, who has announced he is stepping back from royal duties next month.
