开篇是澳洲音乐鬼才Nick Cave的一首温暖而略带感伤的情歌，其间以New Age 手法混入鸟群展翅的原始自然之音，未加修饰却与钢琴之声浑然一体。
To Be By Your Side
演唱：Nick Cave
Across the oceans Across the seas.
Over forests of blackened trees.
Through valleys so still we dare not breathe.
To be by your side.
Over the shifting desert plains.
Across mountains all in flames.
Through howling winds and driving rains.
To be by your side.
Every mile and every year
for every one a little tear.
I cannot explain this.
Dear,I will not even try.
Into the night as the stars collide.
Across the borders that divide
forests of stone standing petrified.
To be by your side.
For I know one thing.
Love comes on a wing.
For tonight I will be by your side.
But tommorrow I will fly.
From the deepest ocean to the highest peak.
Through the frontiers of your sleep.
Into the valley where we dare not speak.
To be by your side.
Across the endless wilderness where all the beasts bow down their
heads.
Darling ,I will Never rest till I am by your side.
Every mile and every year.
Time and distance disappear I cannot explain this.
Dear NO.
I will not even try.
For I know one thing.
Love comes on a wing and tonight I will be by your side.
But tomorrow I will fly away.
Love rises with the day and tonight I may be by your side.
But tommorrow I will fly.
But tommorrow I will fly.
But tommorrow I will fly
