King Charles marks his 78th birthday and the King's Trust's 50th anniversary on Elton John's Rocket Hour, joking that the two are "still standing" while Elton John replies that he is still sitting. His playlist spans 'I'm Still Standing', Calvin Harris's 'Giant', Phil Collins's 'In the Air Tonight' as a tribute, and the Beatles' 'All You Need Is Love', and Elton John credits hearing Elvis Presley's 'Hound Dog' through his mother with setting his career in motion.
