Kick line in Broadway songs. Name for it?

Question for musical theater geeks. I’ve always wondered if there’s a name for that part of Broadway type songs near the end where the music slows down to half speed and the singers all form a kick line while the audience applauds on queue.

Here’s a couple examples.

I always called it a “halftime kickline ending”. Everyone seems to know what it means. Go back four or eight bars and play half time. (half tempo) It’s usually finished with a blues type riff. It happens with the trad jazz bands I play with occasionally.

I didn’t watch the clips.

I don’t know if there’s a formal name for it, but TV Tropes calls it a Last Chorus Slow Down.

I looked in the conductor’s score, which I happen to have, for Pippin’s “Glory” (which is mentioned as a song that has this, and the first song I thought of), and all it says in the notes to the conductor is “blues ride out,” but googling the phrase doesn’t seem to indicate this is any sort of standard nomenclature (though I somehow knew what was meant by that.) There’s no actual kick line in the Pippin version of the song (at least not in the productions I’ve seen), but it’s the same type of slowdown where you’d expect a kickline.

ETA: Actually, listening to your examples, it is perhaps a little different. The ones I’m thinking of are in triple meter rather than duple.
