These tracks were originally recorded in 1976 by the C.J. Mead Organisation, from a Voigt Model 35 69-Keyless Street/Band Organ at Bressingham Steam Museum, Norfolk. Called the Bressingham Voigt, it remained there for many years, but was eventually sold and now performs in the Netherlands. The record was owned by Chris Sawyer's father, and it's tracks were used in both RollerCoaster Tycoon 1 & 2. From what I understand, all of these songs are original arrangements from the Ruth Fair Organ Company.
