It was probably taken from the CD 'We're here because we're here' - a collection of songs from the World War I era, from the trenches on both sides. It's performed by Coope, Boyes and Simpson, along with a chorale group from Paschendale whose name I don't have a record of. It's been performed across Europe and possibly in the US too.

It's an incredible album, well worth a listen or six, very moving and evocative.
