Have there been shows, particularly musicals, where there's a Narrator who's also a character in the show who, when narrating, draws confused questions from other characters who want to know who he/she's talking to? I assume there must be, but I don't remember ever seeing that happen.
Thanks!

In the second act, the Giant that Jack killed has a wife that wants to kill Jack. To satisfy the Giantess, the group realizes they must give her someone, but are unable to decide on whom until they realize that the Narrator is still commenting on the actions from the sidelines. Everyone offers her the narrator as a sacrifice, but he convinces them how lost they would be without him. -Wikipedia
Sonny Malone in Xanadu, while not a technical narrator, does talk to the audience at the start of the show and a few times throughout. He does even end one talk with "...who am I talking to?"

Despite the narration the cast performs in PETER AND THE STARCATCHER, the only character in-story to address the audience directly is Black Stache, who has a habit of saying things like "Could you hurry this up? People have paid for babysitters."
On the National Tour, they devised a very funny bit where a prop was dropped into the audience, and when Stache's assistant Smee jumped off the stage to retrieve it, Stache would react as if he had disappeared and scream "Smee, Where did you go?!!"

Though not quite what you're looking for, in the musical episode of Buffy in which characters have been (unbeknownst to them) cursed to break into song involuntarily, Anya comments in confusion after her song, "It's like we were being watched, like there was a wall missing from our apartment..."
Also, if A Very Potter Musical counts... Quirrell makes some rather expositional comments, ostensibly to Voldemort but really for the audience's benefit, and Voldemort keeps responding along the lines of "I already know this, Quirrell, I hear everything you hear!"
