This is a true story, I recalled it when I took part in the Extreme Challenge last Sunday:

Winnie and her daughter Charmaine were walking on a hanging bridge.

Her daughter was scared. (bridge was shaking at such a height etc)

Then Winnie asked Charmaine to sing a song so that she could feel better.

Agreeing that it's a good idea, Charmaine started to sing "London Bridge is Falling Down"
