Rogers said the message from the choir was to get people talking about mental health and “have those conversations”.
Owen said they were “totally, totally blown away by the words of support”.
“Especially from the farming industry, because that’s the industry and the profession we work in,” he said.
“Even the messages that have come from beyond the community have been immensely touching and it’s amazing to know from that semi-final performance last Saturday that almost our message, our story, has kind of transcended the agricultural industry.”
Roger said they had a good connection with the song they planned to sing in the final.
“If we can get across in the way that we know we really can, and people get behind it, I think it’s going to be a belter,” he added.
He said the whole experience had been surreal and like a whirlwind.
“It’s gone from one thing to another. We can’t believe the traction that this has gathered.”
The choir will perform in the final alongside golden buzzer winner Celestial and teenager Rafferty Coope, from Hampshire.
The final of ITV’s Britain’s Got Talent will be broadcast at 19:00 BST.
