the practice of shouting out the names of various dances in a song - is it retro?

Almost omnipresent in 60's danceable Pop ("Land Of A Thousand Dances", "Nobody But Me", "Papa's Got A Brand New Bag", "Do You Love Me?", etc etc etc), but after that it kind of vanished from the scene - I can't think of many Funk, classic Dancehall, Disco, Dance, old Hip-Hop or Europop songs that do it (I can think of some New Wave tracks, but in an obviously ironic fashion, cf. DAF) I always thought that it had something to do with dancing itself becoming less formalised, like in the early 60's teenagers actually would take the time to learn the Twist and the Hully Gully and all that, and of course there'd be tv shows teaching them how to do all these diferent steps, but then in the late 60's that kinda stopped, due to hippiedom in Rock and Funk/concept albums in R&B, I guess. I suppose it never got revived until now, even after dancing became a bit more formalised again (Disco) because it just seemed too quaint? But also I just couldn't imagine dancers of my generation at least actually taking the time to learn a whole bunch of dances to pass in revue, it's enough of a bother to memorize the macarena or the ketchup song by itself! I do remember girls from my school learning very elaborate choreographies from boy-band/girl-group videos, but those never seemed to be about dancing per se, more like a form of acting (i.e. it was all about pretending to be Ginger Spice, not showing off your ultra-complex moves).

Anyway, it seems to have come back now, as exemplified by the "Yeah!" video and countless recent Dancehall tracks. So what I'm wondering is this: am I right in my analysis, or is there actually a long line of choons keeping this tradition alive that I just haven't heard yet? Also, if I am right, why has it resurfaced now, of all times? Is it self-conciously retro? Is Li'l Jon taking the piss out of/celebrating that whole ancient "American Bandstand" thing, or is he probably totally unaware of the connection? Are the current usages of this pratice meant as a joke/gimmick, or are they actually emulated in clubs and shit? Is it a bit daft to lump "Yeah!" in with the jamican stuff (I know that the evolution of dancing steps was very essential to the development of jamaican music in the 60's)? Do most of the dances that Richie Feelings & co. shout out even exist??
