Is there anywhere I can find a video of Rock And Roll Machine by Triumph from the Stages album?

The version of Rock and Roll Machine by Triumph on the album "Stages" is my favourite version, its like 10 minutes long and the solo is incredible. I would really like to know if a video of this performance exists, if so I'd really like to know where I can get it...Rik Emmett is one of the greatest guitarists of all time, if not THEE greatest, came BEFORE EVH and terribly underrated
