《Heaven Knows》的歌詞如下：
Oh heaven knows what I've been through
Oh heaven knows what I'm thinking of
Oh heaven knows what I've been through
Oh heaven knows what I'm feeling too
(Chorus)
You were my everything
And now you're gone
Without a word
I can't go on
But heaven knows
What I'm feeling for you now
(Verse 2)
It was so hard to let you go
But now I know what I've got to do
It was so hard to say goodbye
But heaven knows how I feel inside
(Chorus)
Oh heaven knows what I've been through
Oh heaven knows what I'm thinking of
(Bridge)
Maybe heaven knows how I feel
Because I've been thinking of you all the time
(Chorus x2)
Oh heaven knows, heaven knows...
