Chris Martin played this song about a Hogwarts student who wants to be in Gryffindor in an event 
for Lumos, JK Rowling's NGO. It's a very funny and cute song, you can check it here

It sounded right, but it's my first tab, so I hope you like it! 


A                     D      A  
I don't care if I'm rich or poor
E                            A
Don't wanna rule the world or start a muggle war
A                             D          D
I just wanna help professor Dumbledore
E                        A
Oh Lord let me be in Gryffindor

A                           D
It's a question with which I'll begin
E                           A
Which house of Howgarts will I be in
A                           D           D
With the sorting hat put me in a spin
E                            A
Oh which house at Hogwarts will I be in

A                   D
I'm ok at Quidditch I'm great with brooms
E                       A
I can apparate between different rooms
A                         D               D
But I don't like ravens of that I'm sure
E                       A
So you can't put me in Ravenclaw

A                       D      A
No I don't care if I'm poor or rich
E                        A
I ain't no wicked wizard I ain't no wicked witch
A                    D       D
I don't wanna be a dementor
E                     A
So Lord let me be in Gryffindor

A                         D
Now the homework here is such a struggle
E                         A
These potions and things so much to juggle
A                               D
There ain't even time for me and Hermione to snuggle
E                       A
And what if it turns out I'm just a muggle

A                              D
And Dolores Umbridge just gave me a grin
E                  A
Draco Malfoy says I'm his twin
A                        D
Professor Snape, he just stroked his chin
E                    A
Oh, fuck it, am I in Slytherin

A                       D       A
No I don't care if I'm poor or rich
E                           A
I ain't no wicked wizard I ain't no wicked witch
A                      D
Now I don't care if I'm wrongly blamed 
E                         A
For naming him who should not be named
A                      D            D
But I don't care for Lord Voldemort
E                      A
So Lord let me be in Gryffindor

A                            D
Now there's a test online to find out this stuff
E                 A
Well surely I am good enough
A                             D
But I took the test and the test was rough
E                  A
And I ended up in Hufflepuff
