Op amp generates square sine wave after noise injection

I found this demo circuit in the LM4562 National Semiconductor datasheet on page 25. A square sine wave is generated, but only when the light bulb is being used and noise is injected into the circuit (by shaking your tablet or phone). Switch to the LED and the sine wave stops until switched back and noise injected again.
