Choosing a background song...

On most of the NSPCC adverts i have watched there has been a narrative voiceover and then quietly in the background some soft music. I have been looking for an appropriate song to go with my images and after researching into various different songs i have chosen 'You are my sunshine' by Elizabeth Mitchell. Even though the music behind the lyrics in this song is quite cheerful i think the words really match what i am trying to show in my images.

Here is the song...

Lyrics...

You are my sunshine, my only sunshine
You make me happy when skies are gray
You'll never know dear, how much I love you
Please don't take my sunshine away.

The other night dear, as I lay sleeping
I dreamed I held you in my arms
But when I awoke, dear, I was mistaken
So I hung my head and I cried.

You are my sunshine, my only sunshine
You make me happy when skies are gray
You'll never know dear, how much I love you
Please don't take my sunshine away.

You are my sunshine, my only sunshine
You make me happy when skies are gray
You'll never know dear, how much I love you
Please don't take my sunshine away.
Please don't take my sunshine away.
Please don't take my sunshine away.

I also would like to add on top of the background sound an overlaying voiceover with text so that it looks like a mock up of an NSPCC tv advert.

The text i would like to be on the voiceover i have chosen based on listening to many NSPCC tv adverts,

Nobody knows what happens behind closed doors

Look for the signs and you could help children in need

lets come together to stop child abuse, full stop.

I am going to overlay this voiceover only when the images of the abuse child come into the video so that this helps the viewers distinguish between the images of the unsaturated colours (happy) and black and white images (abused).

Also when this image is shown in the video...

I am going to attach the sound of the happy family going out of the door and down the stairs to school, so that it shows the abused child we see above is listening at the door of the happy family going out to school.
