Presenter Paul Kirrage is joined by well known mechanical organ builder and music arranger Kevin Meayers to pay tribute to the pioneering mechanical organ preservationist Ted Reed who passed away earlier this week at the age of 96. Paul and Kevin will take a look back at the life of this modest and unassuming gentleman of the fair organ world and discuss the legacy he has left for us all to enjoy as well as playing tracks from several of the instruments from his collection at Amersham.

Enjoy an hour of wonderful Christmas tunes you know and a few you might be surprised to hear on mechanical instruments.
