This song was popularized by The Company in the late 90's. It was also featured in the movie Radio Romance (i think). A quick youtube search informed me that this song was revived by Erik Santos and Sheryn Regis, and was featured in the movie entitled Now That I Have You, starring Bea Alonzo and John Lloyd Cruz. I still prefer the version by The Company.
Now that I have You - The Company
All my life it seemed
That something had been missing
I didn't know what to do
Days would pass me by
Each as lonely as the other
Until I met you
REFRAIN:
You opened the door
And let the sunshine in
My life will never be the same again
CHORUS:
Now that I have you
Everything just seems so right
Now that I have you I'm alive
You are the song that I'll be
Singing my whole life through
I'm living in a brighter world
Now that I have you
Looking ahead I see
The two of us together
I'll never let you go
You're so dear to me
And it isn't any wonder
Why I love you so
REFRAIN:
You opened the door
And let the sunshine in
My life will never be the same again
CHORUS:
Now that I have you
Everything just seems so right
Now that I have you I'm alive
You are the song that I'll be
Singing my whole life through
I'm living in a brighter world
Now that I have you
BRIDGE:
I feel this love is real
I see it in your eyes
You take my hand and I understand
You are mine
You are mine
CHORUS:
Now that I have you
Everything just seems so right
Now that I have you I'm alive
You are the song that I'll be
Singing my whole life through
I'm living in a brighter world
Now that I have you
