My first recollection of ABBA is linked with the song Happy New Year, likely because of that song having had a key part in some televised celebration that got etched in my memory. But this being a wrong season and all, I’ll put up the song that must have been the most popular of theirs in the late 70’s where I grew up. ABBA gained tremendous popularity in the USSR in their heyday and beyond, thus becoming one of the very few singing acts that were known well on both sides of the Iron Curtain.
It should be noted that while I am a fan, I only became such in the 90’s, with CD era in full swing. The recollections of my youth, including a reference or two to the group in contemporary movies, probably played a role in that.
