If you follow your heart, and end with a song."
[elaborate song and dance number]
A film or TV show, despite not previously having been a musical, ends with a Crowd Song (possibly a traditional musical number, more likely lip-synced to an existing recording) involving a significant portion of the cast without regard for the previous relationships (or even physical locations, or even aliveness) of the characters involved. American examples are possibly derived from the straightforward (over)use of this trope in Euro cinema. Bonus points if it uses Vera Lynn's "We'll Meet Again".
Frequently overlaps with Dance Party Ending. Probably related to Big-Lipped Alligator Moment and to Gainax Ending. Contrast with Dancing Is Serious Business. Not to be confused with Musicalis Interruptus, which is when a musical performance suddenly ends.
- Episode 46 of the first series of Magical Princess Minky Momo ends with all the characters who had appeared in the show so far dancing and singing the show's theme song. It'd make more sense if it had been the actual finale.

- Shrek 2 ended with "Livin' La Vida Loca".
- The Blue Sky Studios animated movie of Horton Hears a Who! has all the characters break into Can't Fight This Feeling at the end. According to the DVD Commentary, this was because they wanted to avoid a Bittersweet Ending where Horton has to leave Whoville behind and never talk to the mayor again, and that's all they could think of.
- At the end of Open Season 2, everyone begins to sing "Close To You" after the wild animals and pets settle their differences and become friends.

- Mr. Bean's Holiday ends with everyone on the beach, lip-syncing to the song "La Mer."
- Inland Empire. A nice cherry on top of a film that is Mind Screw all through.
- "Age of Aquarius/Let the Sunshine In" at the end of The 40-Year-Old Virgin.
- There's Something About Mary had the entire cast singing along to "Build Me Up Buttercup", switching around to different locations used in the movie.
- Slumdog Millionaire, as a nod to the film's Bollywood influence. Bollywood flicks are generally loaded with song and dance numbers.

- Bring It On ends with the cheerleaders lipsynching to "Hey Mickey." clip
- Casper, the film, in which at the end the entire cast breaks out into a Little Richard cover of "Casper the Friendly Ghost."
- The final scene of Who Framed Roger Rabbit shows the main cast of the movie and half the population of Toontown parading out of the factory as "Smile, Darn Ya, Smile" plays in the background from out of nowhere. A less out-of-left-field example than most, since the song had been heard earlier and it had already been established that Toontown was a naturally song-filled place.
- Get Over It has the cast singing Earth, Wind & Fire's "September."
- Evan Almighty has the cast singing and dancing to "Gonna Make You Sweat (Everybody Dance Now)" during the credits.
- Beetlejuice rather bizarrely ends with a crowd dance scene to Harry Belafonte's "Jump in the Line". While the film is not really a musical per se, there has been some plot-important singing before that. It's still kind of a non-sequitur.

- An early episode of Kingdom Hospital ended with the medical staff breaking into a musical number, dancing in the OR, corpses in the morgue singing along. It comes completely out of nowhere, and yet for a series that runs on equal parts Surreal Horror and Black Comedy it somehow works.
- 2point4 Children
- Every Christmas Episode of ends with the characters in a parody of a cheesy American Bing Crosby-style Christmas Special, singing 1950s Christmas songs. In the first one, it was justified as an Imagine Spot into Bill's mother's fantasy Christmas. In subsequent years, though, it just happened.
- A more justified example in the episode "Frenzy", which almost ends with Jenny's school talent contest and Ben and David accompanying her singing "Everybody Needs Somebody to Love". Then they get home and discover the house is on fire.
- Season 7A of Mad Men ends with Bert Cooper singing "The Best Things in Life are Free", complete with secretarial backup dancers, completely out of nowhere. It's even more random considering Bert died earlier in the episode.
- In an unusual example of this being played for Tear Jerker, the Scrubs episode "My Philosophy" ends with a patient - who had previously said she liked to imagine death as a big Broadway number - coding. As JD watches, his Imagine Spot has her singing "Waiting for My Real Life to Begin" with some of the regulars. As the song ends, so does the Imagine Spot, and we fade back to the medical team realising they've lost her.

Bugs: Fantastic, isn't it?
