Michael Jackson’s “This Is It” companion album — really just an album of hits — sold a little over 200,000 copies last week and went gold. That means it’s sold over 500,000 copies in two weeks.

The really weird thing is that another greatest hits album from Jackson, “Number Ones,” sold about 33,000 copies, too. Are people just buying and rebuying the same songs? Hey, why not?

Meanwhile, some interesting news from the live performance front: Cirque du Soleil is heavily courting the Jackson estate for a Las Vegas-style show featuring Michael’s music. The Canadian-based company is said to be working hard to convince all the parties that they can do for Michael what they did for the Beatles with the “Love” show at the Mirage Hotel.

The money involved is said to be astronomical.

Right now, Cirque du Soleil is prepping an Elvis Presley show, “Viva Elvis,” which will start performances next month at the ARIA Hotel in Las Vegas. Once that show is off the ground, the Jackson estate will confer with the Cirque folks. Meantime, AEG Live is also hoping to get its “This Is It” show, featured in the movie, on tour in some way as well.
