Your mention of *Enchanted *made me think of the *Trolls *movie(s?). Don’t they perform a song or two because that’s the sort of thing Trolls do when they get together?
White Christmas fails.
Blues Brothers fails.
I’d suggest Hedwig and the Angry Inch. Not the film version, but the stage show set-up is literally just Hedwig and her band, with Hedwig monologue-ing and performing numbers.
The crossover Flash episode ‘Duet’ featured The Flash and Supergirl - in civilian identities - singing songs to each other - and others - while in a coma produced by the Music Meister that forced them to learn about themselves and their feelings for others to escape the coma.
Goofy as hell, but a ton of fun due to the chemistry and charisma of the two leads.
Oh man. For nearly 30 years I’ve thought this was just a lyric in a song by the Look People.
Now I learn it’s about a musical featuring Louis Jordan?! How did I miss this?
The second one fits, IIRC.
How about “O Brother Where Art Thou?”
While I’m not totally sure it qualifies as a "musical’ it does have a lot of characters singing songs and all are in-universe actual songs the other characters are aware of.
Arguably “I Will Get Back Up Again” isn’t diegetic, given that it’s a montage scene. “Hello” is also debatable.
The Cotton Club, maybe?
Yankee Doodle Dandy qualifies, and also Words and Music. Pretty sure Till the Clouds Roll By fits, too.
Not sure if it qualifies, but how about Waiting for Guffman?
Fanwank*: when the dwarfs break out into song in The Hobbit, they are singing a traditional dwarf song that they all know.
Chip the glasses and crack the plates!
Blunt the knives and bend the forks!
That’s what [insert name] hates-
Smash the bottles and burn the corks!
And when Thorin sits down and starts singing about gold, it is a song he has previously composed and rehearsed.
- not that I’m actually a fan of the trilogy, just a figure of speech.
Been awhile since I saw it, but I think Jersey Boys qualifies.
Beautiful also seems to set all its songs at either a performance or showing someone plugging it.
The Commitments?
Star! (1968)
Julie Andrews stars as actress and singer Gertrude Lawrence, and there are many great musical numbers performed on stage as part of the story. Julie Andrews was never better than in this movie.
I’ve enjoyed finding some clips:
Saga of Jenny (spectacular circus number, don’t be put off by the first 30sec)
Playing Gertrude Lawrence drunk (non-musical, but brilliant)
My Ship - exceptional
Likewise, Darling Lili
36 posts and no one mentions Viva Las Vegas?
Most of the songs are during Las Vegas stage shows or rehearsal.
It was on TCM recently and I have that available. Let’s see. Outside of the above: Evlis and A-M sing to each other by a pool, Elvis has a guitar as accompaniment. It sort of fits in with the rest of the Vegas act stuff. An awkward 3-way between Elvis, A-M and Cesare Danova (yeah, right). An Elvis solo set next to a stage after a show which is the hokiest one of all. But other than that, they seem to be all performing for others or rehearsing.
Sadly, William Demarest wasn’t allowed to perform. Oh, well.
Thank you. I was too lazy to look that word up last night, but it’s exactly the word I needed for this thread.
Interesting edge case. Thanks.
Thanks.
I agree with both of these.
Good suggestions all.
Casablanca. Oh, I know some will nitpick that it’s not a “musical.” 
But it has a lot of singing in it, and it’s all in character.
In fact, Warner Brothers actually produced a musical stage production of Casablanca. It didn’t work.
