TV1 - song in advertisment

Please help me identity this song!

I heard it on the background of TV1's (Australian) ad for the station. It was playing in the background of images from the Cosby Show, the Brady Bunch etc.

Parts of the lyrics flash on screen and are as follows (roughly):

"when the sun is in the corner of the sky and the shadow's growing longer in the light"

A female is singing it and it has a "folksy" sound to it.

Any help with be greatly appreciated.

I think it might be this, sorry if it's not!

Into the Future (Words: Carl Dixon Music: Dixon/Curran/Neigher)

Shadows growing longer
It’s cold without the sun
One day you look around
And everyone you know is gone

There’s a light in the distance
There’s a key in the door
And there’s something beckoning
You can’t stay here anymore

Into the future you’ve already gone
Into your wildest dreams where you belong
Into the future you’ve already gone
Long Gone

Fits you like you’ve come home
Hey, where you been so long
Ghosts fade in and out of view
Temptation but you know it’s wrong

In a moment a lifetime
You can never turn back
And what you leave behind
Will fade into the black

Into the future you’ve already gone
Into your wildest dreams where you belong
Into the future you’ve already gone

Hello LikeTheDrink,

Unfortunately it's not the song but "Thank you" for responding.

I'm beginning to wonder whether the song was written specifically for the advertisement and isn't a "real" song.

Thanks anyway.
