Everybody’s talking about: Britain’s Got Talent

One of the stars of last night’s show was teenager Harry Gardner, who won a place in the next round with a moving song about his grandmother, who battled with Alzheimers.

Unfortunately, since he filmed the audition, she passed away, making the performance even more poignant for the audience at home. Heartbreaking.
