While performing at Glastonbury on Saturday, singer Lewis Capaldi made headlines when he headed to The Pyramid Stage to perform his back catalogue of ballads. However, towards the end of his set, Lewis, who was diagnosed with Tourette’s syndrome last year, could be seen struggling with his vocals. Speaking to the crowd, 26 year old Lewis said: “I'm going to be honest everybody, but I'm starting to lose my voice up here, but we're going to keep going and we're going to go until the end.
