A musical tribute to Princess Diana has been released by Haverfordwest Male Voice Choir for charity – and it's been given the Royal seal of approval. Choir musical director Christine Kelly set the famous prayer Ave Maria to a piece of music she wrote last year. Before recording and releasing it the choir won endorsement from Prince William and Harry's office.

"I wrote to the princes saying we wanted to release a CD as a Welsh tribute to their mother and that we wanted to raise money for their mum's charities," said Ms Kelly from Hook.

"Their office wrote back saying the princes were touched by my composition and appreciated us getting in touch with them first."

The recording was launched in the Senedd at a reception hosted by Preseli Pembrokeshire AM Paul Davies. It was compered by Haverfordwest's Brian Harries and attended by broadcaster Roy Noble.

"Releasing this recording is a wonderful way to remember Princess Diana and I was proud to be able to help Haverfordwest Male Voice choir give it the launch it deserved," said Mr Davies.

The six-minute long CD costs £3.70 and is available in Tesco stores. For every copy sold 50p goes to Great Ormond Street Hospital and 50p goes to the Noah's Ark Appeal for the Welsh children's hospital.

"Great Ormond Street was a cause close to Diana's heart and we felt that if she was still alive then she would have supported the appeal for a Welsh children's hospital as well," added Ms Kelly.

The choir has nearly 60 members (the eldest of whom is 91) and they performed the music at the Cardiff launch.

"The comments we had about it included "breathtakingly moving" and "emotional"," said Ms Kelly.

Paul Davies AM added: "This is a fitting Welsh tribute to a Welsh princess and I wish the choir every success in raising a lot of money."
