The Look of Love by Burt Bacharach/Dusty Springfield

Burt Bacharach, who wrote this song, told Record Collector magazine: "I had Dusty sing that very sexy. Dusty was very open to suggestions. To listen to the vocal back with her she'd have to go into a control room to hear it. She wanted to hear it alone. She was very tough on herself. But she did a great job." 
This was not released as a single in the UK. 

The look of love Is in your eyes
The look your heart can't disguise
The look of love Is saying so much more
Than just words could ever say
And what my heart has heard
Well it takes my breath away I can hardly wait to hold you
Feel my arms around you
How long I have waited
Waited just to love you
Now that I have found you
You've got the look of love It's on your face
A look that time can't erase
Be mine tonight Let this be just the start
Of so many nights like this
Let's take a lover's vow
And then seal it with a kiss I can hardly wait to hold you
Feel my arms around you
How long I have waited
Waited just to love you
Now that I have found you
Don't ever go I can hardly wait to hold you
Feel my arms around you
How long I have waited
Waited just to love you
Now that I have found you
Don't ever go
Don't ever go
I love you so
