I think the most irritating thing about Abba’s music is that the songs’ “hooks” are so good, it’s more difficult to rid yourself of them than a salmon trying to throw a treble hook from its mouth.
For example, this one. All the more evocative because it was released just before one of the girls (I forget which one) got divorced.
We went to the ABBA Experience in London last year. I have to admit, it was very good. My son and I still haven’t worked out how they did the hologram stuff, it was like live action puppetry without the strings.
