《once upon a day》的歌詞如下：
When I was young and easy to please
When I was young and had no need to try
I dreamed as all the dreamers dream
And had no care of what might be
And did as all the dreamers do
Once upon a day
Chorus:
Once upon a dream
I knew a land beyond the blue
Where dreams came true
And life was dreams come true
Once upon a time
It seemed so plain to see
That dreams and reality were one
But dreams so often hide the real
And when they come to you
They're more than just a dream
Once upon a day
Verse 2:
Now I'm old and easy to disbelieve
In all the dreams that once I knew
But still my heart remains young and true
And dreams return to me
Chorus:
Once upon a dream
I knew a land beyond the blue
Where dreams came true
And life was dreams come true
Once upon a time
It seems so long ago
That youth and joy have gone away
But memories are all that's left of that
Once upon a day
Chorus:
Once upon a dream (3x)
Once upon a time (1x)
Memories are all that's left of that (1x)
Once upon a day (1x)
