As someone said in the comments, they really don’t make (promote) videos like this any more.

It’s just a beautiful video, someone performed something on stage, the crowd clearly loved it. It required real talent, and wasn’t just done to get Youtube views in a weekly/daily video posts trying only to drive engagement.

A shame that Youtube’s best days are long behind it. Yes the beast is bigger than ever and has so many more people, but it’s not quality rising to the top.
