Well, basically this song is actually in A major, but I play it in C because it's easier I can sing that range better. The equivilant chords, if you want to play it properly, are: C -> A C7 -> A7 C/B -> A/G# G -> E F -> D Fm -> Dm Am -> F#m D -> B D7 -> B7 E -> C# Bb -> G OK let's get to it!

This is my e^Carth, and I ^Glive in it, It's ^Fone third dirt and ^Fmtwo thirds water, And it ^Crotates and revolves through space, At ^C7rather an impressive pace, And ^Fnever even ^Fmmesses up my ^Chair, ^C/B But ^Amhere's the really weird thing, The ^Dforce created ^D7by its spin, Is the ^Fforce that stops the ^Cchaos flooding ^Gin. This is my ^Amearth and it's ^Ffine It's ^Gwhere I spend the vast majori^Ety of my ^Amtime It's ^Fnot perfect, but it's ^Cmine. It's not ^Gperfect.

Pretty much the same throughout, with some notable differences:

This is my ^Chouse, and I ^Elive in it. (same verse has Bb after the last G chord)

Last lines:

This is my ^Ambrain and it's ^Ffine It's ^Gwhere I spend the vast majori^Ety of my ^Amtime It's ^Fnot perfect, but it's ^Cmine. It's not ^Gperfect. ^FI'm not sure I've ^Amworked out how to ^Gwork it. ^FIt's not perfect, but it's ^Bbmine. ^C
