With respect to all those who have tabbed this song in the past in the key of Fm,
this is actually closer to the real thing. Originally it was recorded in a kind of
G, before the whole mix was
sped up one semitone to G# to make the vocals sound 'younger and more innocent'.
However, the song only really works in the key described below which is, to all
intents and purposes, G.

(A note on how the chords are formed)

When played on the piano, the opening chord is constructed of an Em7 with a G bass,
followed by a Dm7 with a C bass. Towards the end of the verse there is more of this
trickery, involving a Gm7 with a C bass and an Fmaj7 also with a C bass. The G9 in the
bridge can be played as A G7, A G6 or A G13,
depending on how you play and what your ear tells you.

What I've called Em7/G is similar to the open G shape, the notes being G, (A muted), E, G, D, E.

What I've done below is the best I can for a song that was designed for piano and not guitar.
