Welsh Choir Practising at Tewkesbury Abbey in 2016 - Thou Wilt Keep Him In Perfect Peace

Showing a tour of the ambulatory and chapels behind the chancel of Tewkesbury Abbey and the beautiful statue by Anthony Robinson: Our Lady, Queen of Peace.
If a member of the choir recognises this please let me know who you are so I can credit you and the organist?
When I posted this a copyright dispute appeared, I thought well that is odd I videoed this mysef?
When the email came through I realised it was about the music, if it had been calledd a copyright claim it might have made more sense!
Anyway I am very happy to ackowledge the stunning piece of music:
