"Their Hearts Were Full Of Spring" lyrics

There's a story told of a very gentle boy
And the girl who wore his ring
Through the wintry snow
The world they knew was one
For their hearts were full of spring

As the days grew old
And the nights passed into time
And the weeks and years took wing
Gentle boy, tender girl
Their love remained still young
For their hearts were full of spring

Then one day they died
And their graves were side by side
On a hill where robins sing
And they say violets
Grow there the whole year round
For their hearts were full of spring
