Tonight, he’s singing the Rodgers and Hammerstein classic ‘You’ll Never Walk Alone’, an iconic song if ever there was one. But it’s all part of a whirlwind that has seen young Jack become a public concern. As he told Classic FM’s Jane Jones, as Royal Northern Sinfonia rehearse Tchaikovsky’s cannon-fuelled 1812 Overture in the Royal Albert Hall upstairs: “It was amazing, it was unbelievable. Sometimes I heard myself on Classic FM and sometimes I saw myself on the TV and thought, is that really me?! It’s weird when you see yourself or hear yourself on radio or TV, but it’s just great to be a part of that event.”
Despite his new-found fame, Jack reveals he’s still pretty self-critical. He may have performed in front of the Queen and at a remembrance concert for the Hillsborough disaster, but he’ll be pinching himself for a while yet.
