What is the John Lewis Christmas advert song 2018?

The John Lewis Christmas advert for this year has not been unveiled.

A video purporting to be the John Lewis commercial surfaced on social media in a now-deleted tweet.

In the video, audiences saw a Christmas tree before the camera panned to an anonymous figure playing the piano and the opening to Sir Elton John's Rocket Man.

It is difficult to tell if the man playing the piano is actually Elton John himself.

John Lewis declined to comment on the footage when approached by Express.co.uk.

If the video is anything to go by, the John Lewis Christmas advert song this year is Rocket Man.

However, it was rumoured earlier this year that Sir Elton would receive £5million to star in the advert.

HAS THE JOHN LEWIS CHRISTMAS ADVERT BEEN LEAKED? 

Sir Elton released Rocket Man in 1972 on his album Honky Château.

The official song title is Rocket Man (I Think It’s Going to Be a Long, Long Time).

It became number two in the UK charts and number six in the US.

Rolling Stone magazine named it as one of the 500 greatest songs of all time.

WHEN WILL THE JOHN LEWIS CHRISTMAS ADVERT BE OUT? 

Bookies are predicting that Sir Elton John will be these year's Christmas number one with his acoustic version of Rocket Man.

In previous John Lewis adverts, popular songs have been slow-downed and sometimes vocals are backed only by piano or guitar.

Last year's song was The Beatles’ Golden Slumbers covered by Elbow. Other years have included Ellie Goulding’s cover of Sir Elton's Your Song and Keane’s Somewhere Only We Know which was covered by Lily Allen.

Bookies across the board have released odds on Sir Elton becoming the Christmas number one.

Ladbrokes have placed Sir Elton at odds of 6/1 and William Hill at 5/1 for Christmas number one.

Coral has put Sir Elton at just 6/1 odds of taking the top spot.

Coral’s Harry Aitkenhead said: “The John Lewis Christmas advert is one of the highlight’s of the festive season and if Elton is indeed the star you can bet he’ll be soaring up the charts once it hits our screens.

“The odds of him landing Christmas Number One have been slashed and could well sink even lower once the advert comes out.”

John Lewis has not released an official air date for their 2018 Christmas Advert.

Their 2017 Christmas advert dropped on Friday, November 10, so it could be as early as this Friday (November 9) that the advert is officially released.

The John Lewis Christmas Advert 2018 is expected to be released later this month
