I'm wondering about this one , now that you have me thinking. My mother used to sing it to me-

I'll buy you a star, not just any star
But the best one in the sky
You'll have a cloud to sleep on
A cloud as soft as an angel's sigh
A fine silver chain made from the rain
Of a summer afternoon
I'll buy you a star my darling
But I won't rest till I buy the moon

Any ideas?
best- Julia
