“Loovley white horse“

Surrey is quite a horsey county, and this establishment is on the outskirts of our village. Developers had their eye on this land a few years back but luckily they were unsuccessful. Like most teenage girls our daughter was very keen on riding and helped at another stable whenever she could.
Whenever I see a white horse I think of Stanley Holloway’s monologue about Waterloo and I can hear his Yorkshire accent as he says “oop rode the Duke on a loovley white horse”. Does anyone know what I’m talking about?
