And a one, and a two, and a one-two-three-four!
There goes Bob and Alice, their mortgage is way past due. There goes Bob and Alice, and soon their day shall be misconstrued. There goes Bob and Alice, General Dusk is watchin' you! There goes Bob and Alice — why hello! I was just doin' a number, a musical number, yessiree!
Y' see, I may be a narrator but I am also a talented vocalist, a singer if you will. Now, if you biddly-boppers pay heed to the Trope Title, then you oughta know that I’m aware of everything that's going to happen in the plot. And what better for me (though not necessarily all the time) to step in for a musical; what good is a musical if the guy tellin' the story ain't singin' along?
Say, baby, if you gon' be lookin' for the singin' narrator ensemble, then go 'head and check out Greek Chorus. For a more general, how do ya put it, categorization of folks with an awareness of the work's fictionality, why don't you go on and take a look at Fourth-Wall Observer. Anyway, back to my mel-o-dee!
There goes Bob and Alice, I know everything they're gonna do. There goes Bob and Alice, I play didgeridoo. There goes Bob and Alice, they'll never make it up to you! OW!!!
- Hercules: The Muses start their takeover for the original narrator, who they say is too boring, by launching into a gospel musical number describing Zeus overthrowing the Titans.
- The Hunchback of Notre Dame (Disney): Clopin opens the movie with the story of how Frollo killed Quasimodo's mother and "adopted" Quasi — despite the fact that Clopin wasn't even there at the time, and the two men (or possibly more, if you count the staring masonry) who were certainly wouldn't have told anyone about what happened. However, for the rest of the film he's just a standard character who knows no more than anyone else. In the Berlin musical production based on this film, Clopin stays the narrator throughout.
- Robin Hood (1973): Alan-a-Dale, the rooster minstrel, plays with this trope because he becomes a character in the story who appears in several scenes.
- Rancho Notorious: The ballad "The Legend of Chuck-a-Luck" is heard during the opening credits and throughout the film, using the lyrics as narration. According to the American Film Institute, this is the first American film to use a song in this manner.
- Repo! The Genetic Opera: The Grave Robber. Of course, he's reading a newspaper about the events of the Opera, so even though he wasn't there, he still knows about certain events. Unfortunately, however, they don't do the same when explaining how he knows all about Blind Mag's contract problems. He actually hands off the newspaper to Shilo while Mag's rival is standing right there at the time.
- The Rocky Horror Picture Show: The Criminologist. Of course, he doesn't actually sing (but he does do spoken word accompaniment during the Time Warp song.)
- The Story of Robin Hood and His Merrie Men: Alan-a-Dale wanders through the early parts of the film singing about events that have just taken place. Even after he joins the Merrie Men, he plays no real part in the action.
- A book of Classical Mythology features a script-version of the story of Achilles. "Chorus" is described as the "Narrator who knows everything".
- Galavant: Jester knows all the plot threads during his summation songs, even if they contain events he was not present for nor could have been informed of.
- Assassins: The Balladeer goes over the three successful attempts we see on stage and, in "Another National Anthem", tries to get the Assassins to be more polite. He fails, and they turn him into Lee Harvey Oswald. One can also count the Proprietor as this as well, as he gives inspiration for the Assassins to start trying to kill their targets, and even interacts with them in some versions of the play.
- Evita: Sometimes he's Che Guevara and sometimes he's just a random everyman, but he serves as both narrator of Evita's life and one of her harshest critics.
- Hadestown: Hermes. Originally his role was just to narrate the show and give Orpheus the directions to the back way into Hadestown, but as the show evolved he's become more and more of a character (such as being responsible for introducing Orpheus and Eurydice in the first place). "Road to Hell (Reprise)" implies that, as a god, Hermes always knew the end of the story was inevitable but was compelled to play his role in it anyway.
- Hamilton: Aaron Burr. Played with in that there are several noticeable blind spots from where Historians has no knowledge. Most tellingly, he starts narrating the facts about the Hamilton-Reynolds affair only to just shrug and let Hamilton take over narration a few lines in. We then cut to a description from (the historical) Hamilton's own highly biased writings.
- Into the Woods: The Narrator is all-knowing, since he has a book that tells how every story is meant to end. Things get considerably worse when he dies.
- Natasha, Pierre, and the Great Comet of 1812: Everyone gets a turn narrating their own actions or the actions of others from the third person.
- Pacific Overtures: The Reciter sings of Japan's feudal ways and the country's modernization and encounters with the West.
- Headless: A Sleepy Hollow Story: Downplayed with Diedrich Knickerbocker. While he does sing his narration of Ichabod's story to the audience and appears to be only seen and heard by Ichabod, he is not entirely all-knowing — there are a few instances where he sings that something is about to happen, but doesn't actually know what it is. He's more Narrating the Present in this sense.
Diedrich: (singing) But before he could start to sob and cry
A welcome visitor would soon stop by...
Ichabod: (happily) Really? Who?
Diedrich': What? Oh, I don't know.
- Arthur: Parodied in "The Ballad of Buster Baxter": "Mom, there's a singing moose in front of the house!" (Said singing moose is no less than Art Garfunkel.)
- Central Park: Birdie is a busker who also serves as the show's narrator. He explains to the audience there are certain rules to being a "narrator": the main one being that despite being an actual character in the show, he isn't allowed to be a narrator of the interactive variety and directly interfere with the plot. He actually gets briefly replaced in the episode "Rival Busker" after he breaks this rule by impatiently blurting out plot details to Paige.
- Pinky and the Brain: Pinky does this briefly in "Brainy Jack", until Brain tells him to stop in a Left the Background Music On moment.
