The Oxford-based charity helps children with life-shortening conditions and their families.

The concert will feature performances from Frideswide Voices girls’ choir and the Lay Clerks of Christ Church Cathedral.

The University of Oxford’s a cappella group, Out of the Blue, will also perform and debut their 2024 Christmas single.

There will also be festive readings from families supported by the hospice, as well as from Mr Blanc and actor Anthony Calf.

“I’m honoured to be part of the Helen & Douglas House Christmas Concert, sharing the spirit of the season and supporting the vital work they do in our community.”
