I just got off the phone with this guy.  His name is Dominic Fragman.  He puts together these "one man band" videos and has had great success.  His last video was him doing Rush's "Tom Sawyer" and Dominic told me he got 3 million hits on Facebook and over 700,000 hits on YouTube.  Check out this video of Dominic doing Led Zeppelin's "Black Dog".  Enjoy!
