Buy Harvest King: Dancing in the Moonlight
Light it is, this theme around.
If you're going to classify your lights, moonlight is possibly the most romantic of all lights, closely followed by firelight, candlelight - and some folks would include firefly light. And if you are going to classify your hits, you might take a moment to consider why King Harvest is not remembered for the original version, but TopLoader is for theirs.
I won't lay claim to being a great fan of these guys: TopLoader, but that won't stop me from promoting this song for our theme, either. In fact, (probably like you) all I know about them is that they have this one hit song. But I will give them kudos for coming out with this. Note: not coming up with, but *coming out* with it: although they are the band best remembered for the song, it isn't their composition: it belongs to King Harvest (who?!?) However, like them or not, (their version of) the song is catchy - and that's probably why it became more popular than the King Harvest original. For that matter, it strikes me that it isn’t all that unlike some other songs that took someone to the big time (Please, Please Me &c) in relation to the lack of depth of its lyrics.
Of course, there are many ways to rank your musical preferences other than "best" or "original" - and even then, you are walking a thin line in calling *your* definition of best/original the same as other people's! I recall a t-shirt I bought in the 60s that said "Cool is as cool does" - and I guess that applies here. Harvest King wrote a decent song, TopLoader made it "cool".
To the extent that SMM aims to enlighten its audience, let me add a hidden gem in the way of a version that you would be unlikely to run across unless you followed my "trail". To me, this clip is so, so typical of what it means to be on the stage as an amateur musician: acceptably competent, but everyone just walks and talks right past them. Make your own comparisons: "tightness" of the band, showmanship, backup vocals …what else is it that makes a song/a band a hit?
For that matter, The Rolling Stones' Moonlight Mile (a totally different genre/emotion) is equally a best as a "moonlight" song, n'est ce pas?
