King Charles marked his 78th birthday by appearing on Elton John's Apple Radio show Rocket Hour for a special recorded episode celebrating the 50th anniversary of his charity, the King's Trust. Joking with the 79-year-old singer, the King said they were "still standing", and John quipped "I'm still sitting now, though", prompting the King to add that there were "occasional bits dropping off here and there" as people get older.

The pair built a playlist of 14 tracks that the King said reflected the charity's history. Charles chose John's "I'm Still Standing" in recollection of its performance at the trust's Rock Gala at Wembley Arena in 1986 for its 10th anniversary, when he said "we and the Trust are definitely still standing". Other picks included Calvin Harris and Rag'n'Bone Man's "Giant", chosen for the idea of drawing strength from those who came before, and Phil Collins's "In the Air Tonight", in tribute to Collins, a trust supporter who was being inducted into the Rock and Roll Hall of Fame as a solo artist that Saturday.S1S2

The selections also highlighted the trust's role in giving young people their first break. Charles recalled that in 1994 a group then known as the Rocket Baby Dolls received a small grant from his trust to buy audio equipment, and later, as Muse, became one of the biggest stadium bands in the world. Rising star Nectar Woode, whose track "Wine Into Water" features John on piano, has been supported by John since she sent him a demo tape early in her career.S1S2

Asked to name a song he found especially meaningful, Charles chose The Beatles' "All You Need Is Love", recalling its performance by Paul McCartney and other stars at the Golden Jubilee Party at the Palace concert in 2002 in honour of his mother, Queen Elizabeth II. "Well, there can surely be nothing more meaningful than love," he said.S1S2
