Does anyone know what show im thinking of

I saw an episode of a pretty old tv show a while ago it might have been back in like the 80’s and it was similar visually to [this](https://www.youtube.com/watch?v=z7Da2j3\_0Gw). People would submit songs and there’d be an accompanying video, the artists name at the bottom. Lots of country stuff sang by farmers. I think there were presenters in between songs. The episode I saw one song had a song sent in from Australia though I think he was Irish, and the video was shot in like a zoo or crocodile farm that you could visit or something. Probably misremembering a lot of details but I remember part of it was him sat in one of those miny trains like the one in the pavillions and he was singing away as it passed the camera.

Was this all a fever dream or can anyone help
