Not really anastasia, but here’s a lovely video of Derek Klena singing a re-worded ‘Part Of Your World’ as Dmitry at 54 Below’s The Broadway Prince Party
CONSIDER THIS: Mermaid Princess Weiss, sneaking onto the beach of the nearby city, singing "Part Of Your World" from "The Little Mermaid." She surfaces and sits on a rock at the end, "When's it my turn? Wouldn't I love, love to explore that shore up above? Out of the sea/ Wish I could be / Part of that world..." and then Human Seashell Collector Ruby finally tells her she can hang out with her if she likes.
