People expressed their fondness of both the singer and the situation in the comments.

One person said: "Everyone singing is a blessing to this world. Thank you."

Another commented: "He makes me melt. This is so raw and beautiful."

A third added: "Not me learning he has Tourette's! Wow. This song is even more beautiful."

The star has been open about his Tourette's Syndrome.

Most recently, he made a video in response to concerns for his well-being to reassure fans that he is alright.

He said: "I've got Tourette's so I'm just twitching quite a bit but it's not an issue in the slightest. I'm absolutely fine.

"It's just that this happens when I get tired, nervous, excited or whatever so it just gets more intense."
