BBC 1 Northern Ireland will air a programme entitled Voices 16 – Somme this coming Wednesday at 9pm. I don’t know if it is available in other BBC regions, but it will presumably be available on the BBC iPlayer afterwards. Sadly, however, BBC is very strict in not allowing viewers in other parts of the world to watch iPlayer.
