The Deagan Organ Chimes were patented in 1900 in Chicago, Illinois. Each of the 8 chimes has 3 octaves of a single note, which completes a C Scale. The Deagan Chimes were made by J.C. Deagan Company in Chicago around 1901. Bub Thomas joined the Dapper Dans in 1970 and brought in the Deagan Organ Chimes, having used them in previous quartets. Bub was taught how to use them from a woman named "Billie Bird" who was a Vaudeville performer as they worked together in the 40's-50's.
The Dapper Dans have made several media appearances on TV over the years and with Disney's "Limited Time Magic" in 2013, The Dapper Dans were a piece of the magic by changing their musical line from Barbershop to a "Boy Band" lineup including groups like One Direction & New Kids on the Block. I hope that you do look for the Dapper Dans while in Disney parks and stop to enjoy the sweet A Capella sounds from the past and smiles to your face.
