I have a special affection for this organ, since I visited the Wanamaker’s Department Store on many occasions as a child, and once had the thrill of hearing my grandmother play the organ. At that time, she (Mrs. Daisy Corr Clinton) was the organist at the Central Congregational Church in Philadelphia. She had the reputation of being able to read a book while playing the music for church services. I suspect she was concentrating fully on this incredible organ when she played it.
