A-Ha may be the most popular Norwegian pop act ever so of course I know them quite well. I was quite fond of Memorial Beach when that came out (I was a kid then basically so it's a while ago), but haven't really been an active fan since then. Still, their hits are a nostalgic and slightly guilty pleasure.
Of their old hits, I think this is the one I enjoy the most.
I find it hard to not think of Morten Harket as a bit douchey in a pretentious sort of way, but the guy can definitely sing.
