I think Busty Pixie only did a few photo sessions (more's the pity). In one of them, the person doing the video carried on while she was adjusting her clothes so there is a brief topless video of her. As I remember from the time, she was not very happy about this as the whole thing was meant to be tease. Pity.
I had a thought when watching the 19 and topless video. When she gets to the point where shes bares everything I kind of expected applause or something. I mean there's so much build up, teasing and slips over the years that it was kind of anticlimactic once it was released to us. I guess this is why she didn't go topless years ago.
