A Song of Everlasting Regret

A great wonder shall befall,

When heaven and earth do meet,

From ancient times it has been told

Of this love of ours so sweet.

In the Tang Dynasty of old,

In the Palace of Eternal Spring,

Amidst the blossoms and the gold,

A love was born that made hearts sing.

The Emperor Xuanzong and Yang Yuhuan,

A love that burned as bright as the sun,

But their passion was doomed to end,

For the winds of change they could not fend.

As the years did pass them by,

Their love did slowly fade,

Until the day came when they did sigh,

For all that they had made.

And so it was that love did die,

A tragedy for all to see,

For even those who reach so high,

Are not immune to destiny.
