The choir was originally founded by Clarkson as part of an advertising campaign for his Cotswolds-based brewing firm.
Since then, the group has remained together and used its platform to help raise awareness around mental health in farming.
After entering Britain’s Got Talent, judge Amanda Holden pressed her golden buzzer following the ensemble’s performance on the Saturday evening show in May.
The 30-strong group of farmers got a free pass to the semi finals of the ITV talent show and won the £250,000 cash prize in the final – including the opportunity to perform at the annual Royal Variety Performance in November.
The members described Clarkson, who was in the audience for the live final, as their “biggest cheerleader” and added they “couldn’t thank him enough”.
