The X Factor judge visits Camp Bastion in Helmand Province to gain an insight into life at the military base and perform a morale-boosting concert for an audience of around 1,000 members of the British armed forces. Joined by the Royal Artillery Band, he sings some of his own hits and other favourites, including Michael Buble's Home and He Ain't Heavy, He's My Brother by the Hollies. The Take That star also joins the team in the air-traffic control tower, steps into the driving seat of a huge heavy-equipment transporter, and heads out on an early-morning run with the troops.
