He had made an enviable reputation for himself with Firefly, the showman's steam engine he owned in the seventies; Little Lady, the Foden steam lorry; but most of all with Prince, his scaled down Burrell steam engine, and Ceol, his fairground organ built by the Chiappa family.
Leonard and Ceol toured from Aberdeen to Cornwall and in the process raised £120,000 for charity, appeared on BBC Television's Playschool, and cut three records of organ music.
Mister Organ Man is the story of Leonard's life from his childhood pranks with steam engines to his adult years as ambassador extraordinaire for steam and for fairground organs. It is a story that will appeal to the child in everyone of us.
