If you invest your tuppence wisely in the bank | Safe and sound | Soon that tuppence, safely invested in the bank | Will compound! | And you'll achieve that sense of conquest | As your affluence expands | In the hands of the directors | Who invest as propriety demands | “Fidelity Fiduciary Bank”, Mary Poppins (1964)
