The premise seems to be there’s a sort of competition between couples of who can dance the longest, eventually couples start dropping (I’m not sure if they died or collapsed from exhaustion), until finally one couple is crowned winner in the end, the winning couple seems to jump off a plank into the sea (or something??) the singer is playing the piano, I think he’s wearing a suit.
I vaguely remember one of the lyrics as something like “and she boxed Mars” or something sort of like that. I feel like the bands name had Sam in it, but I could be misremembering. It’s driving me crazy that I can’t remember the name, band, or really any of the lyrics!
