New trades and entertainments became dependent on resourceful immigrants from poorer countries: in the early 19th century, Italian organ-grinders multiplied through London, with their monkeys.

Charles Dickens, among others, got organ-grinders banned from the streets of London once upon a time.
I remember with a peculiar vividness an organ-grinder who came around with a monkey, and the accuracy with which the monkey could catch a ball.
