Do You Want to Build a Snowman? - Siblings Cover

After watching Disney's "Frozen" and loving it, we realized that each sister is at an age that fits perfectly into one of Anna's verses for the song "Do You Want to Build a Snowman."
With the addition of our wonderful brother who we finally convinced to learn the piano chords for us, we put together our own siblings version of this beloved song!
Lyrics:
Elsa?
(Knocking: Knock, knock, knock, knock, knock, knock)
Do you wanna build a snowman?
Come on lets go and play
I never see you anymore
Come out the door
It's like you've gone away-
We used to be best buddies
And now we're not
I wish you would tell me why!-
Do you wanna build a snowman?
It doesn't have to be a snowman.
(Go away, Anna)
Anna:
Okay, bye...
(Knocking)
Do you wanna build a snowman?
Or ride our bikes around the halls
I think some company is overdue
I've started talking to
the pictures on the walls-
(Hang in there, Joan!)
It gets a little lonely
All these empty rooms,
Just watching the hours tick by-
(Tic-Tock, Tic-Tock, Tic-Tock, Tic-Tock, Tic-Tock)
(Knocking)
Elsa?
Please, I know you're in there,
People are asking where you've been
They say "have courage", and I'm trying to
I'm right out here for you, just let me in
We only have each other
It's just you and me
What are we gonna do?
Do you wanna build a Snowman?
