Worst Cover Song Ever

Indeed, this is horrific.

French-Canadian chanteuse Celine Dion is responsible for the world's worst cover version -- a rendition of rockers AC/DC's "You Shook Me All Night Long" -- Total Guitar magazine said in a poll.

Dion has never released the song as a single but performed what the magazine called the "offence" against music at a Las Vegas concert six years ago in a duet with Anastacia.

"The number one worst cover song -- Celine Dion covering AC/DC -- is sacrilege," said the magazine's editor, Stephen Lawson. "The best covers are unlikely choices and they do something radical."

Clips of Dion and Anastacia rocking are available on the Internet video-sharing website YouTube. One of the comments that doesn't use strong language read: "My poor ears."

This one also made the list. So bad it's good. Clearly, a cheesy spoof.
