Fresh video footage of

Michael Jackson

rehearsing for his

This Is It

comeback tour has been released.

The 45-second never-before-seen footage shows the King Of Pop rehearsing and choreographing his stage moves for

Human Nature

from hit album

Thriller

.

The brief clip has been released by Sony ahead of the feature doco

This Is It

, which is based on extensive rehearsal footage of the star preparaing for his 50-night run at The O2 Arena in London.

Jackson, who died aged 50 after suffering a cardiac arrest on June 25, can be seen busting a few of his trademark moves in the clip, as well as singing a few lyrics from

Human Nature

.

Despite his thin frame and gaunt appearance, Jacko actually looks and sounds remarkably confident for a man who was supposedly ravaged by insomnia and prescription drug abuse.

To be frank, it's just a crying shame he snuffed it only days after this was filmed. What a waste.

Check out the video below:

This Is It

will be released worldwide on October 28 with a limited two-week run.

Tickets to go on sale on Sunday, September 27.
