There will also be performances from the likes of Dan Smith, Griff, Katie Melua and Cornish folk music group, Fisherman's Friends.
Ted Lasso star Hannah Waddingham had been scheduled to perform, but just as guests started to arrive, it was confirmed that the actress had been forced to withdraw; her replacement is singer Zak Abel. HELLO! understands that Hannah dropped out after her voice became compromised due to her busy work schedule; she will still be attending the service as a guest.
The concert will also pay a special tribute to the late Duchess of Kent, who passed away at the age of 92 on 4 September 2025. During her life, the late royal was involved in music education, and in 2004, she co-founded Future Talent to help musically gifted children from disadvantaged backgrounds.
