There is credence to ongoing speculation that Michael Jackson might be booked for a long engagement at the O2 Arena in London, though no deal has been reached nor performances contracted.

There is credence to ongoing speculation that Michael Jackson might be booked for a long engagement at the O2 Arena in London, though no deal has been reached nor performances contracted.

But a source confirms that there is a "standing offer with no expiration" from AEG Live for Jackson to play at the O2. The 02 is operated by Anschutz Entertainment Group, and any Jackson stand at the 02 would almost certainly be promoted by AEG Live, the live entertainment arm of AEG.

AEG Live previously promoted long and hugely successful runs at the O2 by Prince and Spice Girls.

Jackson has rarely performed in public in recent years. Last week, he denied a claim by his brother Jermaine that the entire Jackson family would convene for a tour in 2009. Sources say Michael's decision not to participate may stem from his desire to do his own touring next year.

In related news, it was a banner week for Jackson's seminal 1982 album "Thriller," which jumped 41-1 on Billboard's Top Pop Catalog Albums chart after selling 31,000 copies in the United States, according to Nielsen SoundScan (a 1,000% increase).

The set is 2008's top-selling catalog album, having shifted 688,000 copies.
