This is how I remember playing this one. I've labelled it Chords as the tab parts 
are small and just extras.

Note that NC = No Chord (i.e. stop playing for a second or two). 
//// = play that many down-strokes.
The two riffs are non-essential, but I think they sound good in it; they are best 
played by a second guitarist.

VERSE 1
C        G              Am        E
Autumn days, when the grass is jewelled
         C       G      Am      E
And the silk inside a chestnut shell
C          G              Am           E
Jet planes meeting in the air to be refuelled 
           C       G       Am       NC
All these things I love so well


CHORUS
NC           C   G    Am   E
So I mustn’t for-get
              C       G    Am   E (Riff 1)
No, I mustn’t for -  get
    C      G           Am    
To say a great big thank-you!
   E          F  / / / /
I mustn’t forget. 


VERSE 2
Clouds that look like familiar faces,
And a winter’s moon with frosted rings.
Smell of bacon, as I fasten up my laces
And the song the milkman sings.

CHORUS

VERSE 3
Whipped-up spray that is rainbow-scattered,
And a swallow curving in the sky.
Shoes so comfy though they’re worn out and they’re battered,
And the taste of apple pie.

CHORUS

VERSE 4 
Scent of gardens when the rain’s been falling,
And a minnow darting down a stream.
Picked-up engine that’s been stuttering and stalling,
And a win for my home team.

CHORUS

Riff 2
