is joined by a very special guest for his latest show – .

In a truly remarkable turn of events, the latest person to join Elton John’s Rocket Hour will be His Majesty The King, recorded at Apple Music’s new state of the art London studio.

The episode will premiere on His Majesty’s 78th birthday (airing at 9am GMT Saturday, November 14th), and it was actually the first to be recorded at the new Apple Music Radio studios in Battersea, London.

The recording took place in October, with The King sitting down alongside Sir Elton before the launch of the Apple x King’s Trust Creative Labs, a new series of specialised workshops to help equip young people with the technology, resources and in-demand industry skills needed to realise their potential and move into work.

Celebrating 50 years of music and The King’s Trust, Sir Elton John says of the recording: “I learnt a lot from speaking to His Majesty. Hearing about the artists who have been involved in The King’s Trust reinforces the great work that has been done over the last 50 years. I know from presenting my Rocket Hour show, that if you champion a young artist and show you believe in them, it makes all the difference. That’s the greatest thing you can do. Young people are our future and the King’s Trust are doing a wonderful job…”

During the episode, His Majesty says: “Music has always been at the heart of The Prince’s, and now The King’s Trust. So when I was asked whether I would like to showcase a selection of music from among the many talented performers who have so generously supported us over the years, together with some of the newer artists The Trust has helped to launch, it was an opportunity too good to resist.”
