为什么顺子在《写一首歌》的歌名后面要加上1969 April 5?

april 5,1969是顺子《写一首歌》的歌英文版

april 5,1969(顺子)

歌词如下：
When the moon falls in your eyes
I know the sun has set
And the fire still burns within me
Since the day we met
I know my heaven would be so cmoplete
You can make it real
I wont let this chance go by
I can see,I can feel you,feel you,feel you

Oceans apart,the rivers run deep
We still live out love
It doesnt matter how many layers
Of clouds float above
We found each other in the roughest of weathers
Went through every season together
Still wishing the days were shorter
Writing tons and tons of love letters
Love letters,love letters

Oh,my love’s in the air
It’s everywhere
Everyone can see and everyone can feel
That my love’s in the air
It doesnt matter where

Everyone agrees
Love is all we need
