Have you seen this version of Disco Dancer? It even has a topless clip: https://www.youtube.com/watch?v=wa0DB7-jhzI
I only discovered it in the past year.
Also did you see the the restored “In the Beginning Was the End: The Truth About De-Evolution” that Nicholas Winding Refn had done last year?

I’m really looking forward to your project and I love the clip you posted.
