Lyrics:

You ought to know by now
Love is the look in my eye
Lovin' the way you smile when I say
'I wish you would stay'

You bring out all the youth in me
I laugh and cry out all the truth in me
Out o' love
You should know by now

Haven't you felt by now
Just what it's like to be loved?
Knowin' that certain touch when you're sure
Time won't give you more

You bring out all the best in my
I wanna hold you till you feel the need somehow
Somehow, you should know by now

If I could just find the words
I wouldn't be left so lonely
I'm your one, my only
Then I'd show you how
Every move as smooth as silk
Say you will, say you will

Hasn't it crossed your mind?
Haven't you known all the time?
Honestly tell me now, has it shown?
How much love is grown

The way I tremble at the sight of you
I want to learn to love you through and through
This I'll beg, you should know by now
Hmm-mmm

By now, you should know by now
Don't you think you should know by now?
Ooh
