So. It’s Christmas -almost - and of course you hear all the songs.
My question is WHY are there added echoes to the song Rudolph the red nosed reigndeer? Where did they come from? Why is that the only song (except for jingle bells’ -now that I think of it - added “ha ha ha”)
Do any of the other songs have echoes?
There was a time, iirc from the mid-50s to the mid-60s, when lots of echo chamber was very popular in songs. “Who put the Bomp” by Barry Mann or “Downtown” by Petula Clark for examples.
The phenomenon the OP is referring to is a variant of Call & Response.
I first encountered it in a New Orleans-area public high school, circa 1985. I subsequently introduced my older siblings and ~5y.o. nephew to the responses during a shopping trip that winter and quickly got them doing the responses with me.
On the other hand, I join in loudly and enthusiastically when the song comes on the radio during the five-week 24/7 Christmas music festival that I love…
No reference in Wikipedia, but I remember the bar crowds in Long Beach, LI singing “So good, so good, so good!” in call/response fashion to Neil Diamond’s “Sweet Caroline” in the late 80s-early 90s.
I recalled caroling once and some people insisting on doing the echos… so then I would add my own in later to songs where they didn;t fit… just at the end.
“Sleeeep in heavenly peeeeeace… LIKE A LIGHTBULB!”
