音乐剧《猫》的主题曲《memory》
Midnight, not a sound from the pavement
Has the moon lost her memory
She is shining alone.
In the lamplight the whithered leaves collect at my feet
And the wind begins to moan.
Daylight, see the dew on the sunflower
And a rose that is fading
Roses wither away
Like the sunflower I yearn to turn my face to the dawn
I am waiting for the day
Now Old Deuteronomy, just before dawn
Webber Andrew Lloyd
Through a silence you feel you could cut with a knife
Announces the cat who can now be reborn
And come back to a different jellicle life
Memory, turn your face to the moonlight
Let your memory lead you
Open up, enter in
If you find there the meaning of what happiness is
Then a new life will begin
Memory, all alone in the moonlight
I can smile at the old days
I was beautiful then
I remember the time I knew what happiness was
Let the memory live again
