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
