‘I had the most brilliant and illuminating two and a half hours with John Sparks today in which he helped me overhaul my entire musical! It was a wonderful session and I drank it all in! What a great and supremely wise guy. I can’t TELL you what an absolute delight he was! I couldn’t believe that he was giving over so many pearls of wisdom at the critical stage of my new musical and, as I said to him afterwards, my learning curve was vertical! That was simply the BEST musical theatre tutorial I have ever experienced and that session with John was alone worth my membership of MMD and MTN combined! He brilliantly helped overhaul my show at a very critical stage.’ Barbara Jane Mackie, MMD Member
