[talk] BTS flying across the open concert stage

This is a video from 8 years ago, but BTS sang "Blood, Sweat & Tears" at a concert held in 2016.

I've never seen BTS appear on an open concert live before.

There must have been a lot of people who started a blood, sweat, and tears parody craze and followed suit.

It's an old song, but it's a song that I don't get tired of. It's a good song even now. I guess I have to listen to it carefully to understand the content.
