Your supposed to buy the CD and then after each concert a few tracks will be released for download from the queenzone website.
The only problem is nothing has been put on the site for download yet. Despite previous news items saying that they will start 48 hours after the Paris Concert (which was on the 30th).
And as far as I know nobody who ordered the CDs have received them from the queen shop yet.
Theres lots of people waiting see other threads on this site.
