I was under the impression that this deleted sequence no longer existed in any form, but I stumbled across it on YouTube while looking for Russ Meyer trailers and vintage burlesque clips to post on my friend Julie's MySpace page.
Although visibly older, Chesty actually looks better (and more lively) here in than she does in her Doris Wishman movies, although the "better" part may because almost everything but her face and bosom is covered up, so there's no visible pot belly or thunder thighs. But I certainly don't recall her ever moving this energetically in a Wishman film, where she always seems 'luded out.
The footage is part of an interview with Fellini. Chesty doesn't unleash the "big two" until it's a few minutes into it. Sadly, I don't speak Italian, so I don't know what the Maestro is saying.
