I saw GFR around 1969 in Cincinatti at a place called the Ludlow Garage. When everyone else was still trying to get their hair to touch their shoulders, Mark Farners hair almost touched his ass! They were the total Head Band. Loud and totally energetic.Being a guitar player, I loved his riff driven melodies. And if I'm not mistaken, he was playing a Sears Silvertone guitar!! They were and still are inspirational musicians in my book.
