During the My Name is Prince exhibition at The O2, , 'never before seen' concert footage of Prince's run at The O2 was shown in the VIP section while the acoustic guitar was behind handed around.

The tracks shown were Controversy and Purple Rain. We were told that Controversy was from the 2nd night and Purple Rain from the final night.

The visibility of the purple glowsticks would appear to confirm that is correct for Purple Rain. But the Controversy performance seemed remarkably similar to the one shown on Sky News on the final night (same outfit, I believe).

I don't seem to have an audio copy of that second night to compare. Can anyone confirm this?
