There are a lot of good guitar versions of this song, but nothing for the ukelele. 
So I thought I would put one out there for the ukelele, with the small changes I've been using. 



Let it Go - Idina Menzel

Capo 1st fret



    Em                      C   
The snow glows white on the mountain tonight
      D               Am
Not a footprint to be seen
  Em            C       
A kingdom of isolation, 
       D                  Am
and it looks like I'm the Queen
Em          C                 D              Am
The wind is howling like this swirling storm inside
Em               D                    A
Couldn't keep it in; Heaven knows I've tried
D                                 C      
Don't let them in, don't let them see
                                    D
Be the good girl you always have to be
                                    C
Conceal, don't feel, don't let them know

Well now they know
 
        G         D                      
Let it go, let it go
      Em               C
Can't hold it back any more
       G          D
Let it go, let it go
     Em                C
Turn away and slam the door
G       D
I don't care
             Em       C
What they're going to say
        Bm         Bb      
Let the storm rage on,
C                               G  D
The cold never bothered me anyway

Em                      C
It's funny how some distance
      D               Am
Makes everything seem small
        Em                 D
And the fears that once controlled me
      A
Can't get to me at all
D                           C
It's time to see what I can do
                                D
To test the limits and break through
                                 C
No right, no wrong, no rules for me
C
I'm free

       G          D
Let it go, let it go
     Em                    C
I am one with the wind and sky
       G          D
Let it go, let it go
       Em           C
You'll never see me cry
G      D
Here I stand
    Em     C
And here I stay
        Bm         Bb
Let the storm rage on

C                             C7           C       G
My power flurries through the air into the ground
C                                        C7
My soul is spiralling in frozen fractals all around
D                            D7          D
And one thought crystallizes like an icy blast
Em        C
I'm never going back,
D                  Am      C
The past is in the past----
       G          D
Let it go, let it go
          Em                     C
When I'll rise like the break of dawn
       G          D
Let it go, let it go
     Em              C
That perfect girl is gone

G      D            Em         C    (Cm)optional
Here I stand in the light of day------
        Bm         Bb
Let the storm rage on,
    C
The cold never bothered me anyway
