Alt. rock song - need help...

Okay....Ive spent hours on Google now - and Im still lost, so I hope that someone in here are able to help me

I have some of the lyrics and the song is from an episode of the tv-show "Las Vegas" (Episode 3 in season 3, ( Double down triple threat - intro song))

Goes something like this:

there she smiles
back at me
the way she were before
id give anything if only it could be
the way it was before
.....
.....

Refrain:
say hello
say goodbye
......
weve been so behind
say hello
say goodbye
......
weve been so behind

If anyone can help me out here, it would be much appreciated

Thanks...

Maria

PS: Sounds like something between Lifehouse and Our Lady Peace - perhaps some Chris Cornell - but tried all Audioslave with no luck The episode is from Oct 2005

Maybe, this one?

Vulpine "Persona"


Whenever she smiles back at me
The way she would before
I'd give anything if only it could be
The way it was before

The feelings are taking over me
Like who else am I supposed to be with you
'Cause I'm all alone

(Chorus)
Say hello, say goodbye, and walk away
And leave this all behind
Say hello, say goodbye, and walk away
And leave this all behind

I'm reluctant to be here now
The way it was before
I'm beginning to see her smile
The way she would before

The feelings are taking over me
Like who else am I supposed to be with you
'Cause I'm all alone

(Chorus)
Say hello, say goodbye, and walk away
And leave this all behind
Say hello, say goodbye, and walk away
And leave this all behind

The feelings are taking over me
Like who else am I supposed to be with you
'Cause I'm all alone

(Bridge)
Lucky to see another day
What else am I supposed to say to you
And it still be the truth?

(Chorus)
Say hello, say goodbye, and walk away
And leave this all behind
Say hello, say goodbye, and walk away
And leave this all behind

YEEESSS!!!!! Great....thx a lot....you are the best
