As part of the dedication of the Ahlborn-Galanti organ at Christ Church in Vero Beach, a lecture-demonstration was presented by Baden Griffin, donor, and Brady Johnson, Organist and Choir Master.   The lecture included descriptions of an American E.M. Skinner organ, a French Cavaille-Coll organ,  the 1741 Albertus Hinsz Dutch organ from the Netherlands  and an English Brindley-Foster that can be played virtually using Hauptwerk software. Brady chose appropriate repertoire to perform on each virtual organ.  Joseph Rumsberger, an organ student, assisted Brady as a digital registrant on a laptop computer.   Pictured l-r:  Baden Griffin, Joseph Rumsberger, and Brady Johnson.
