We all in the New York City metropolitan area got our love for player
pianos and our start in the hobby from John Duffy and his business,
Duffy Player Pianos, in Palisades Park, New Jersey.

  "Popular in the Roaring Twenties, the instruments were making
  a nostalgia-fueled comeback, and Duffy Player Pianos became the
  nation's largest seller and repairer."
