Spice Girls video

Because curiosity always gets the better of me, I just watched the Spice Girls new video. I think I'm missing something...at what point in the video do they take their clothes off? One minute you've got Ginger with her head in Vicky B's lap having her hair stroked and the next BAM they're in their bras. Is there an adult version of this video? A sort of Spice Girls go crazy in lesbos? Seriously though (feminist cap on), why was it integral (it's clearly not!) to the video that they tops came off and the bras came out? And I also find it interesting that Baby Spice doesn't strip down. Was this out of choice or the fact that she was pre-pregnancy and there would be uproar if she let the bump loose, or was she post-pregnancy and therefore had not regained the washboard stomachs of the other mothers? Who knows but I find it kind of disturbing, especially when I think it's affiliated with Children In Need. Yeah, that's just what the children need..."Mummy, mummy...why are the Spice Girls in their underwear?"
