John Farnham - Help. This guy is a household name in Australia, but almost unknown abroad. In this clip, he’s just given a Three hour, high energy concert and is called out for an encore. He performs this.
More recently, The Dø there is something really special about this performance. This version of Hangover is much better than the recorded version in my opinion.
All of the Blogotheque videos are pretty incredible, something for almost anyone to find compelling.
