Taylor Swift debuting new song 'Ronan' live at Stand Up To Cancer 2012.

Taylor Swift debuted a new song entitled 'Ronan' during a performance tonight at the 2012 'Stand Up To Cancer' event.

Swift wrote the song for a four-year-old boy called Ronan who passed away from a battle with Cancer, after reading a blog from his Mother who helped her write the song.

'Ronan' lyrics:

"I remember your bare feet,
Down the hallway,
I remember your little laugh,
Racecars on the kitchen floor,
Plastic dinosaurs
I love you to the moon and back,

I remember your blue eyes,
Lookin' into mine,
Like we had our own secret club,
I remember you dancin',
Before bed time,
Then jumpin' on me wakin' me up,
I can still feel you hold my hand,
Little man,
And even the moment I knew,
You fought it hard like an army guy,

Rememeber I, leaned in and whispered to you,
Come on baby with me,
We're gonna fly away,
From here,
You were, my best, friend,
For years,

I remember the drive home,
When the blind hope,
Turned to cryin' and screamin',
And why, flowers fell up in the worst way,
Don't know what to say,
To a beautiful, your dyin',
And it's about to be Halloween,
You could be anything,
You wanted if you were still here,
I remember the last day,
When I kissed your face,
And whispered in your ear,

Come on baby with me, we're gonna fly away,
From here,
Out of this curtain, this room, oh this house of grey,
We'll just disappear,

Come on baby with me, we're gonna fly away,
From here,
You were my best, friend,
For years,

And what if I'm standin' in your closet,
Tryin' to talk to you,
And what if I can't the hand-me-downs you don't fit into,
And what if I really thought, some miracle would see us through,
But maybe the miracle, wasn't even getting one moment, with you,

Come on baby, with me, we're gonna fly away,
From here,
Come on baby, with me, we're gonna fly away,
From here,

You were my best, for years,

I remember your barefeet, down the hallway,
I love you to the moon and back."
