The cutest vid you'll see today

Frozen is one of those kids movies that are so good even adults will enjoy it (nothing like the 90 minutes of torture that was the latest Smurfs film).

Being the kids' film of the season, its theme tune Let It Go has become the 'Blurred Lines' for under 10s in terms of hype (just way more inspirational and a lot less degrading).

Disney is meant to spread joy, and nothing has brought us as much joy so far in 2014 as this video of sisters Maddie and Zoe crooning along to the song by Idina Menzel. The performance is made all the more stunning when, at the end of the video, you discover the ailment one of the girls has been suffering from throughout her rendition (the show must go on). 

Here are the lyrics so that you can sing along with the girls:

The snow glows white on the mountain tonight

Not a footprint to be seen

A kingdom of isolation, And it looks like I’m the Queen

The wind is howling like this swirling storm inside

Couldn’t keep it in, heaven knows I tried

Don’t let them in, don’t let them see

Be the good girl you always have to be

Conceal, don’t feel, don’t let them know

Well, now they know

Let it go, let it go

Can’t hold it back anymore

Let it go, let it go

Turn away and slam the door

I don’t care

What they’re going to say

Let the storm rage on, The cold never bothered me anyway

It’s funny how some distance

Makes everything seem small

And the fears that once controlled me

Can’t get to me at all

It’s time to see what I can do

To test the limits and break through

No right, no wrong, no rules for me

I’m free

Let it go, let it go

I am one with the wind and sky

Let it go, let it go

You’ll never see me cry

Here I stand

And here I'll stay

Let the storm rage on

My power flurries through the air into the ground

My soul is spiralling in frozen fractals all around

And one thought crystallizes like an icy blast

I’m never going back

The past is in the past

Let it go, let it go

And I'll rise like the break of dawn

Let it go, let it go

That perfect girl is gone

Here I stand In the light of day

Let the storm rage on,

The cold never bothered me anyway

And here's the original song ... and as you can see from the 31 million + views it's been on high iPad rotation ...
