Worst Christmas song ever?
US comedian Ed Bassmaster might just have done the worst ever cover of Mariah Carey's All I Want for Christmas is You.
Ed, well known for his YouTube parodies, pranks - and singing very badly in public - has come up with another gem.
This time it's Christmas themed: a rendition of Mariah Carey’s All I Want For Christmas Is You.
Sung badly in public, again.
We're not sure what's funnier: his voice, or the reactions of all the people around him.
