Stupidly, I didn’t shazam this song when I heard it.
The lyrics I caught (and they repeated a few times) were the first few lines of “I’m in Love with a Wonderful Guy.” (“I expect everyone of my crowd to make fun…”) But the music/style sounded really alternative-y to me. It may just be a remix that samples those few lines.
When I search, all I get are lyrics and cast recordings of “South Pacific,” and unless someone has radically re-imagined the show, it’s probably not from a production. Does anyone recognize/know the song?
