Me either, youd think with all the media coverage they would have videotaped the dance, not just Travolta, but Reagan, Eastwood, Sellick, etc. where other times she danced with the Prince were taped.
Now, I could be off base, but maybe the palace press secretaries didnt want to fuel any more of her solo popularity, dancing with stars. Just that it seems odd that so much of the trip and others had video of big events, and whenever the two of them danced, they had video. Maybe they felt it was "unprincessly" to show her dancing with a man other than her husband in video, idk it was 30 years ago.
Shame though, it was such an iconic moment and with her gone would have been a delight to watch, so if anyone has links, please share
P.S. I have a feeling if she was still around she'd have rocked the show "Dancing with the Stars' for one of her charities
