Troops in Afghanistan are enjoying some festive cheer thanks to their very own choir.

The UK Joint Force Medical Choir has been boosting morale in the run-up to Christmas with some entertainment for fellow troops, including a carol service at the hospital in Camp Bastion, the UK's main base in Helmand Province.

The choir, who call themselves Only Medics Allowed, is predominantly made up of members of 203 (Welsh) Field Hospital, who staff the medical facility.

It was only set up at the start of the tour a few months ago but has gone from strength to strength.

Founder Captain Lyndon Davies, who is an officer in the Queen Alexandra's Royal Army Nursing Corps, came up with the idea.

He said: "I've always had a love for singing myself. I sing in a choir back home - the BBC National Chorus of Wales - and when we've been going away in the mission, specific training and readiness for this mission, we always got people together and had a bit of a sing-song back home."

Sergeant Donnie "Bomber" Harris, from the Isle of Lewis, had never sung in a choir before.

The 36-year-old, an operating department practitioner in the ANSF Medical Development Team, said: "I had a little deal with Captain Davies that I would come and sing in his choir if he would come to the gym.

"I kept up my end of the bargain and he's not been to the gym once.

"For me, to start with, it was just a bit of fun but then we started taking it seriously because we actually started sounding really good."
