Nothing to feel guilty about. They were a pop band of genius.
Agreed!
I was about 3 or 4 when they were at their mid/late ‘70s zenith. My half-Swiss cousins were huge fans and when I visited their house at the time, it was wall-to-wall ABBA music blaring full-tilt. I can’t hear a single song of theirs without being transported back 30 years ago...
Of course, when ABBA folded, they started blasting Toto... :-P
