Intro is similar to chorus
D, A, G twice
D, F#, G
Then the last line of the chorus, A, G, A, D

Verse.
[Em]I used to have a [B7]secret cellar
[Em]Where I kept the [B7]sweetest of my [Em]wine
Now it seems that [B7]I've been too long
[Em]Hanging on the [A]vine
(Chorus)
And now she's [D]turning it [A]into [G]water
[D]Never be the [F#]same a[G]gain
She's [D]turning it [A]into [G]water
[A]All my [G]]wine tastes [A]like the [D]rain

(Bridge thingy)
[F]Go bar the [C]cellar door
[G]Throw out the rusty [Bflat]key
[F]Won't go there [C]anymore
There's [G]nothing there to [Bflat]see
There [G]is no mystery [Bflat]y
(Al switches the order of these last two lines later)

(Magic transition into Instrumental)

The instrumental chords (and the fade out sequence) are an interesting
variation on the tune.They change in the same places as in the chorus but
they're different.

E minor,  A,  D, G,
E minor, F#, B (yes, B!)
