Anybody recognize this lyric? It's a children's song, learned by my informant in the USA in the late 1930s.

A little boy read in a wonderful book
Bickety-backety-book
How faerie-folk dwell in a dell by the brook
Brickety-brackety-brook

O-lea O-lay O-loo-loo My Darlin'
Children have quizzical ways
O-lea O-lay O-loo-loo My Darlin'
And some keep them all of their days

He came to a man who was mending a hook
Hickety-hackety-hook
Poo Poo said the man as his finger he shook
Shickety-shackety-shook

O-lea O-lay O-loo-loo My Darlin'
People forget they were small
O-lea O-lay O-loo-loo My Darlin'
They think they are wise because they¹re tall
