The Glastonbury teen-sensation Alex: The best time of my life

“I walked off stage and the security guards took me back down and it was just amazing. The way security brought me back down was in front of everyone and I was walking past people who were screaming my name. I had the best time of my life” - fifteen-year-old Alex Mann tells Guardian about performing a song at Glastonbury next to Dave. He rattled through every word of Dave’s complex 'Thiago Silva' tune, and after the performance “lots of people have started following me on Twitter and Instagram and liking all my posts … I am not going to let it get to my head too much”.
