Lewis Capaldi's fans step in to finish song as he experiences Tourette syndrome tics on stage during concert

Lewis Capaldi's fans have thrown in their bid as the best in the world after helping the singer through an on-stage incident.

The touching moment came as Capaldi was singing his hit song, Someone You Loved, at his Germany concert on February 21.

During the last part of the song, the singer began experiencing tics as a result of Tourette Syndrome, which he was diagnosed with last year.

Catching this, the fans seamlessly continued on from where Capaldi let off, with him holding onto the microphone both in an attempt to steady himself and in gratitude.

In further thanks, the singer threw his extra guitar picks into the crowd so some of them could have a memento of the beautiful moment.

Capaldi opened up about his diagnosis last year in an Instagram Live.

"I do the shoulder twitch a lot. And you see underneath every TikTok and stuff, people are like, 'Why is he twitching?', which is fine. Curiosity is fine. I get it," he said.

Though the singer says he has had symptoms of the syndrome for years, for him it's still "a new thing".

"I haven't really learned much about it. I'm learning. I've got Botox on my shoulder to stop it moving. It worked for a bit," he said.

"The worst thing about it is when I'm excited, I get it; when I'm stressed, I get it; when I'm happy, I get it. It happens all the time.

"Some days it's more painful than others and some days it's less painful. It looks a lot worse than it is. Sometimes it's quite uncomfortable … but it comes and goes."
