In '66 I'll tell you Sir,
A man called Francis Chichester
Sailed out one day from a Devon cove,
To circumnavigate the globe.

Ch.: Hey ho, roll and go,
Around the Horn in the months of snow,
How many times can a man defy
The raging sea and the rolling sky?

Away from the cheers of a following crowd
Comes Gypsy Moth like a flying cloud
Around Cape Hope with a lazy motion
Straight for the heart of the Southern Ocean

Ch.:

The steering smashed and the progress slow
The RT batteries are running low
They'll never make it straight they said
Here she comes around Sydney Head

Ch.:

A quick refit and a welcome meal
With half a ton of lead in her keel
And out where the roaring 40's blow
Where the ice runs thick and big whales go

Ch.:

Around Cape Horn where the mermaid moans
Straight for the locker of Davey Jones
Where a million tons of ocean hurled
You swear you're bound for another world

Ch.:

Its off to the Gulf Stream warm and mild
With half the nation going wild
Gypsy Moth comes home from sea
So make her fast to the Greenwich Quay

Ch.:
