 Vox Humana 

Heh! I wish I played the organ - but my mother is an accomplished organist and a Fellow of the Royal College of Organists. She plays a large and fine pipe organ built in 1889 by the famous London firm of Henry Willis & Sons to a specification of thirty-nine stops on three manuals and pedals. The instrument is tonally unaltered, and has a Vox Humana, a most beautiful (and surprisingly useful) stop. I run three music pages on MySpace which have recording of this organ:
César Franck
Johann Sebastian Bach
Julie Ainscough (my mother)
I hope these are of interest to you. - Vox  8' "
