Since I haven't seen any tabs/chords for this song, 
I thought I'd go ahead and submit a tab for it 8D \:D/
These may not sound 100% correct, but I think it's somewhat close. :3
Please tell me if there is anything to be corrected~ 8D
Thanks and enjoy~ :)

Intro: Cadd9 D Em7 Cadd9 [3x]
       Cadd9 D Em7 Am C

Cadd9 D Em7 Cadd9 [3x]
One starry, starry night in July
Saw a shooting star fall from the sky
Even the rain’s falling on my head
Cadd9 D G
Wish you'd fall for me instead

Cadd9 D Em7 Cadd9 [3x]
Shook the branches of an old oak tree
Leaves came falling all over me
But what's the matter with gravity?
Cadd9 D G
Why won't it make you fall for me?

Cadd9 D Em7 Cadd9 [3x]
Up, up, down, down
Up, up, down, down
Up, up, down, down
Cadd9 D Em7 Am C
Up, up, down, down

Cadd9 D Em7 Cadd9 [3x]
As the world turns round and round
Just about everything falls to the ground
The lizard on the ceiling fell on my bed
Cadd9 D G
Wish you'd fall for me instead

Cadd9 D Em7 Cadd9 [3x]
I fell down the stairs, I fell down the tree
But it doesn't really bother me
But what's the matter with the gravity?
Cadd9 D G
Why won't it make you fall for me?

Cadd9 D Em7 Cadd9 [3x]
Up, up, down, down
Up, up, down, down
Up, up, down, down
Cadd9 D Em7 Am C
Up, up, down, down

Interlude: Cadd9--D--Em7--Cadd9 [2x]

Cadd9--
Why won't it make you,
Why won't it make you,
Em7--
Why won't it make you fall for me?
Cadd9--
Why won't it make you,
Why won't it make you,
Em7--
Why won't it make you fall for me?

Cadd9 D Em7 Cadd9 [3x]
Up, up, down, down
Up, up, down, down
Up, up, down, down
Cadd9 D Em7 Am C
Up, up, down, down

End on: Em7
