I googled it too! In 1967, I was at Shipham Primary School in Somerset> I remembered the older girls playing a skipping song very similar to this one. The words as I remember them from my five year-old self were:

Green gravel green gravel
Your boyfriend is calling
He sends you a message to tell you the weather
Turn your back you saucy cat and say no more to me!
We shall tell your mother for kissing ...(name)..down in the
parlour!
How many kisses did he give you?....etc
