Tonight, at 8PM in Graham Chapel, Thomas Murray will present a concert of organ music that was once played on the now Wanamaker organ. That organ, in abbreviated form of only 10,000 pipes, was played daily at the World's Fair here in 1904. Since it moved to Philadelphia and was installed in what is now a Lord and Taylor store, over 18,000 additional pipes were added. The composer featured tonight is Guilmant, a french composer, who himself played the great organ at our world's fair.
