Mr. Dawes Sr.:
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 (cough) as propriety (cough) in demands (cough)

Mr. George Banks:
May I, sir?

Mr. Dawes Sr.:
Carry on, Banks.

Mr. Banks (Mr. Dawes Sr.):
You see Michael, you'll be part of...
Railways through Africa (Exactly!)

Fleets of ocean greyhounds (More, tell them more!)
Majestic, self-amortizing canals (How it fires the imagination!)
Plantations of ripening tea all from...

Mr. Banks, Mr. Dawes Sr., and the Bank Directors:

Prudently, thriftilly, frugally invested in the...

Soon you'll see
That it blooms into credit of a generous amount
Semiannually

And you'll achieve that sense of stature
As your influence expands
To the high financial strata
That established credit now commands

You can purchase first and second trust deeds
Think of the foreclosures!
Bonds! Chattels! Dividends! Shares!
Bankruptcies! Debtor sales! Opportunities!
All manner of private enterprise!
Shipyards! The mercantile! Collieries! Tanneries!
Incorporations! Amalgamations! Banks!

Mr. Banks:
You see, Michael...

Mr. Banks, Mr. Dawes Sr., and the Bank Directors:
Tuppence
Patiently, cautiously, trustingly invested in the...
