Guest Lynne King said it was a "spectacular affair" involving family friends, relatives, neighbours, former workers, farming colleagues and people with business connections to the farm.
"Barry related some of the history of the farm, everyone shared memories, talked to people they hadn't seen for years and enjoyed a barbecue meal.
"Rob Yule and his team did their usual superb job of catering and volunteers ran the bar and handed around nibbles," she said.
Takings from the bar went to the fund for a cochlear implant for Lily Hooper of Greytown and to Greytown Early Years.
A rolling display of photographs showed pastoral scenes of the farm, people, dogs and machinery from the past and the magnificently renovated 149-year-old homestead.
Musicians Jamie and Nick Morrison were crowd pleasers with their beautiful acoustic music, and guest Christine Pitt did a great karaoke spot. At dusk a bonfire was lit in the paddock, and thankfully Cyclone Lusi was nowhere to be seen. From Thomas Kempton snr the farm passed to his son Thomas jnr then to Frank, Victor and on to Barry Kempton.
