purchase [Da Doo Ron Ron]
There are two ways to look at a non-sense song:
(1) it makes no sense to anyone, but that's the whole point of it
(2) it makes no sense to you and me, but it had meaning to thems that wrote it
The story goes that Phil Spector chose the nonsense lyrics "da doo ron ron" because they were "dumb enough" not to interfere with the actual lyrics telling the girl-meets-boy story (and that Sonny Bono was there to give his approval).
Among the various options to the <non-sense> theme, this one seemed particularly appropriate because ... welp ... we need some diversionary non-sense to help us survive these days of gibberish from all corners of the world, and <da doo ron ron> makes as much sense as everything else we are hearing. And because the song just brings bouncing happy feelings whenever I listen to it.
I wonder if I have an element of the Trump "things were better back in those days" virus, or if things really were better back then (just see how many "old" songs are still covered)
The Crystals were no one-hit group; Phil Spector made sure of that. Wikipedia reminds us that they were "one of the defining acts of the girl group era in the first half of the 1960s". Another of their hits you probably know is <Then He Kissed Me>.
Speaking of non-sense, Phil Spector's tactical games flip-flopping the Crystals and the Blossoms is one step short of non-sense and likely would not fly far these days.
