Famous Disco song, part of lyrics from chorus

[aaaa]

I've listened this today on a radio, and it is simply amazing.

Part of the chorus:

You dont know
how much you mean to me
You dont know how much you
meeean to me
ah ah ah ah, oh baby

This is all from the lyrics that I can remember right now. And sorry if I wrote something wrong, I'm not very good at english.

Any help is appreciated!

Regards,

I found it, is George McCrae - You Don't Know.

The Lyrics:

Three weeks ago I met you, baby
Oh, what a thrill you gave me
Now I hear you got to go away
Oh, babe, I need you every day
You don’t know how much you mean to me
You don’t know how much you mean to me
Ah, ha, ha
Oh, babe
Ah, ha, ha
Oh, babe
It was only yesterday
When you and me were together in every way
We shared a time of love and happiness
Oh, I’m gonna miss these days, yeah
You don’t know how much you mean to me
You’ll never know how much you mean to me
Ah, ha, ha
Oh, babe
Ah, ha, ha
Oh, babe
But if you really have to go, whoa
You’re alone, I have to stay, I know
Oh, it’s time like these that I’ll ask "Why"
The one I really love has said "Goodbye," oh
You don’t know how much you mean to me
You’ll never know how much you mean to me
Ah, ha, ha
Oh, babe
Ah, ha, ha
Oh, babe
Ah, ha, ha
You don’t know now, yeah, yeah
You don’t know, yeah, yeah
You don’t know now, ah, ah
You don’t know
Mmm…mm…
How much I love you
You don’t know, oh, baby
You don’t know, hey
You don’t know how much I love you
You don’t know how much I need you
You don’t know, you don’t know
You don’t know, yeah, yeah
You don’t know, you don’t know
You don’t know, yeah, yeah
You don’t know, oh, oh
You don’t know, yeah, yeah
You don’t know, oh, oh
You don’t know, yeah, yeah
You don’t know, oh, oh
You don’t know, yeah, yeah
You don’t know, oh, oh
You don’t know, yeah, yeah
You don’t know, oh, oh
You don’t know, yeah, yeah
You don’t know, oh, oh
You don’t know, yeah, yeah
You don’t know, oh, oh
You don’t know, yeah, yeah
You don’t know, oh, oh
You don’t know, yeah, yeah
