Kirsty Young's castaway is the singer Alfie Boe.
He is one of our most popular tenors and, highly unusually, is a sell-out success in both opera houses and musical theatre. The youngest of nine children, he left school to work as a mechanic - before being plucked off the shop-floor for stardom. However, while he's at home on the stage, you won't necessarily find him in the stalls: "I like good singers, I don't necessarily like one genre of music, I just like good singers, good voices and good songs," he says, adding: "I never go to the opera.... it's just not my world."
