I highly doubt they would've rehearsed part way through the tour when they were doing the same setlist they'd been doing for a month. The rehearsal footage is from May, or maybe early June.
That footage seems to be the rehearsal footage that was released on the live Wembley DVD as an extra and was shoot by one of the roadies. It was recorded before the Magic Tour.
Yeah, it's available on the 2-disc version. I have it and it states before the footage that it was shot before the tour began, so a while before Wembley. Don't you have the dvd's, Greg?
