Benanti, who has made a hobby of creating hilarious, self-deprecating Youtube videos about her alleged adventures as a non-household-word Broadway star, continues with this piece.
Radio City's Youtube channel describes it thus: "Laura Benanti is joining a Radio City Stage Door Tour as a surprise celebrity tour guide. However, the tourists aren't quite as excited as Laura, and she leads them on a meandering, improvised and mostly erroneous tour of the Great Hall. Spoiler alert: they make it out... eventually."
Here are earlier clips in the series. In the first, Benanti tries to work out with the Radio City Rockettes. In the second, she tries her hand at making trendy hot drinks as a coffee shop barista.
