I saw you dancing in the dark
Shadows on the floor
Made my heart beat a little faster
I don't know why, I can't forget
Your moves so electrifying
When you come closer
Baby I just can't help but let you know
Chorus:
I saw you, I felt you, I took you in
From the first moment
Every second with you, every night
Is something I'll remember forever
I want you, I need you, I love you
You know that I do
So baby don't ever let me go
