Ben Chick, a farmer based in Sixpenny Handley, Dorset, said performing on Saturday “was the most exhilarating experience”.
He said waiting to find out if they had got through to the final was tense.
“It really does mean the world to us,” he said. “There were people in tears, including me.”
Abbie Condon, a farmer from Witney, Oxfordshire, said: “I was having a bit of a rough time this time last year when the choir all started.
“It’s just given me this shining light to look at the whole time.
“There’s always something on the cards for the choir to be doing and that’s just really picked me up.”
