Hey I must say that twinkie is the best organist that I know, not saying because my mother and her mother was best friends but because she has skills, and she has placement, she learned how to play from a guy named Ronald kersey who is orginally from canada, who played with mattie moss clark during her early years with southwest michigan state mass choir, and also Dr. Clark Played as well, so she is by far one of the best, also Billy Preston, is known for his work and early years with James Cleveland, I was digging in my old albums(LPs) and found a album from the mid 60's that billy preston did on the savoy label, and that organ sounded good then and sure does sound good now
