But why does it look like it was filmed in the 70s?

Awesome.

I'm inclined to believe most of the audio is not of them actually playing, which is unfortunate. I'd have liked to hear their actual performance.

I was initially just surprised at the sound quality for that kind of outdoor setting with very little ambient and crowd noise. When the synchronized singing (from the crowd or "plants" in the crowd with their lip movement not matching up? um) became clearer, that's what really made me suspicious.
The acoustic quality sounds much more to me like a music hall than outdoors, as well.

Viddy well, little brother.

All I could think of was John McClane jumping off an exploding sky scraper.

Sweet.
