They are electronically tagged, just like the Wembley show, but not only did they lose the list of tags, but Michael never left them to the Estate. So a lot of it is up in the air, and what they do find, it was because they got lucky. They filmed the making of the BAD album. All apart of the documentary, that will never see the light of day, the way it's going. The estate has the documentary film. They just don't have all the concert films. Everything filmed was placed on to VHS for Michael to watch. But the vhs tapes were never taken care of correctly and got lost in 93 because of Allegations in Neverland. So the vhs tapes they do have are very bad quality.
