LONDON: A video of a girl singing You Are My Sunshine - with her mouth firmly closed - is going viral online.

Somehow, she manages to enunciate every word of the 1940 classic, best known by country singer and politician Jimmie Davis. The video, entitled The Closed Mouth Singer, has notched up nearly 3.7 million views on YouTube.

It’s not known how the girl learnt that she had such an unusual talent or whether she can sing any other songs with her lips closed.–WO
