Here we go........... 
B5        F#5     G#5   E5 
I wish I had a Sylvia Plath 
B5      F#5    G#5   E5 
Busted tooth and a smile 
B5              F#5    G#5    E5 
And ciggarette ashes in her drink 
B5             F#5                G#5 
The kind that goes out and then sleeps for a  
E5 
week 
B5             F#5              G#5       E5 
The kind that goes out on her own 
B5            F#5         G#5     E5 
To give me a reason for well I dunno 

(Chorus) 
A5                      E5 
Maybe she'd take me to France 
F#5                               B5 
Or maybe to Spain she'd ask me to dance 
A5                              E5 
In a mansion on the top of the hill 
F#5                                    B5 
She'd ash on the carpets and slip me a pill 
A5                                  E5          
Then she'd get me pretty loaded on gin 
F#5                       E5 
And maybe she'd give me a bath... 
G#5                E5       F#5  
How I wish I had a Sylivia Plath 
And she and I would sleep on a boat 
And swim in the sea without any clothes 
With rain falling fast on the sea 
While she was swimming away, she'd be winking at me 
Telling me it would all be OK 
Out on the horizon and fading away 
And I'd swim to the boat and I'd laugh 
I gotta get me a Sylvia Plath 
(REPEAT Chorus) 
I wish I had a Sylvia Plath....
