Blind Contour Friday

Hi everyone, I'm back from my trip to San Francisco! One of the things I did while there was see John Mayer in concert at The Fillmore and as the room was pitch black except for the stage and I could barely see my paper because of all the people standing in front of me blocking out the light, plus I have nothing else prepared and I'm pooped I thought that I would submit this only very slightly cheating, really I could barely see at all sketch I did of him for this week's "Blind Contour Friday".
