Nicholas Ralph, who plays James Herriot, and his co-star Rachel Shenton, who plays Helen Alderson, have been confirmed for the main stage over the three-day festival, where they will be sharing stories from the set.
The duo have been joined by Yorkshire-born celebrity chef Karen Wright, who shot to fame on Great British Bake Off, as the final line-up for the festival is confirmed.
The stars will join the likes of Amanda Owen, The Yorkshire Vets Julian Norton and Peter Wright, and TV chef Tim Bilton at the festival, which is taking place on the August Bank Holiday weekend.
The event is taking place at Cannon Hall Farm in Barnsley, where This Week on the Farm is filmed, and the main stage event will see adventurer Ben Fogle perform his ‘Tales From the Wilderness’ show live, and the stars of This Week on the Farm Rob and Dave Nicholson will also perform their show: ‘Rob & Dave: Oh ‘eck Live!’.
Dog trainer Graeme Hall' 'The Dogfather', Amanda Owen's ‘The Yorkshire Shepherdess Live’, and ‘The Yorkshire Vet Live: It Shouldn’t Happen to a Yorkshire Vet’ will also be performed on the main stage.
Stefan Gates of ‘Secrets of Your Supermarket Food’ series will perform ‘The Mindblowing Gastronaut Show!’ and Adam Henson will be sharing his tales of farming life, with his original show, ‘My Life on the Land’.
In 'The Barn', visitors can join in with live Q&As with Ben Fogle & Amanda and Reuben Owen and meet their favourite animals from the show in a ‘behind the scenes’ experience.
Cannon Hall’s very own chef Tim Bilton, as well as Amanda Owen, will be cooking up a Yorkshire feast on the 'kitchen stage', while 'the allotment' will be the area for all green fingered fans featuring TV gardener, Tayshan Hayden-Smith.
There will also be activities for children with appearances with characters from Fireman Sam, Peppa Pig and Paw Patrol.
