Considering I didn't ride when I was a child and nobody in my family has much to do with horses, I was wondering how and why I ended up hooked.
This could be the answer - found on YouTube. I loved this programme when I was little and it's still one of my favourite ever songs. There's a better clip on YouTube, the actual starting sequence from the show, but I can't work out how to get it from there to here.
Another great TV series for horse-mad girls was Follyfoot. I wasn't into this programme so much but loved the song, I still do.
