I don't rule out the possibility that this contract had some terms referring to the crew's obligations aside from the O2 shows, which also applied in case the tour was cancelled for any reason.
AEG would want to recoup as much as possible from any alternative profits.
One of these terms that are definitely active is the confidentiality pledge which fully expains why no public statements were made by the TII crew.
I sure hope they are on the witness list for the trial and that this overrules any business deals.
I also expect to see some statements after their contracts expire.
