From my teenage years to the present time I have always enjoyed listening to the organ, whilst knowing very little about its workings.
I was recently given an 'Introduction to the Organ' voucher as a birthday gift, and I learned so much from the experience!
To anyone with a modicum of interest in the organ, I can highly recommend that you join Richard for a session. He doesn't ask you to do anything difficult (which was a relief to me!), and he is very gentle and patient, as well as being extremely knowledgeable!
