Working Man - RUSH, Live 1974

First known recording live of Rush playing at Laura Secord Secondary School in Ontario. With original drummer John Rutsey. GREAT guitar work - really jamming with a bit extra in there than the album.
And they STILL play that with the same type of energy 40 years later. Video from 2011 at the Gorge that I and my 16-year old son went too (row 16)! (Not my video, though)
