Michael Jackson Estate Acknowledge Paul Anka Wrote New Single

Michael Jackson's new single This Is It was actually written in 1983, it has emerged.

Representatives of Jackson's estate were forced to make the acknowledgement after songwriter Paul Anka revealed he had written the track with the singer.

The pair penned the track – originally called I Never Heard – for a duets album Anka was recording, and were also credited as co-authors on an early 1990s version by the singer Sa-Fire.

However, This Is It was not initially credited to Anka when it was given its world premiere on Monday.

"They did the right thing," Anka told the Press Association.

"I don't think that anybody tried to do the wrong thing. It was an honest mistake."

Anka has now been credit for the song and will receive 50% of the track's profits.

A statement from the Jackson estate said: "The song was picked because the lyrics were appropriate because of the name Michael gave his tour.

"We are thrilled to present this song in Michael's voice for the first time and that Michael's fans have responded in unprecedented numbers."

This Is It is taken from the soundtrack to the forthcoming Michael Jackson movie of the same name.

The movie shows footage of the late singer, who died in June,  preparing for his ill-fated comeback gigs in London.
