D5                                                        G5
When there's a burning in your heart
                 D5                                  G5
An endless yearning in your heart
           D5                                    
Build it bigger than the sun
                  G5
Let it grow, let it grow
                       D5                                G5
When there's a burning in your heart
                            D5
Don't be alarmed

ETC, once you get the rhythm down it's easy as pie. The chorus carries the same rhythm

BRIDGE 

A5
And if you feel just like a tourist in the city you were born
G5
Then it's time to go
A5
And define your destination
                                                             G5 (changes to major) 
There's so many different places to call home

etc etc

Hope this is okay, i might update it later if i figure out a better sounding way! cheers.
