[Intro]
Eb F Bb Eb
Cm Cm7 Cm6
D E7

[Verse]
F#m
You look different every time
F                   Am                                 Em
You come from the foam-crested brine
F#m                 F                 Am                 Em
It\’s your skin shining softly in the moonlight
F#m                 F                 Am                 Em
Partly fish, partly porpoise, partly baby sperm whale
F#m                 F                 Am                 Em
Am I yours? Are you mine to play with?
F#m                 F
Joking apart
Am                                                 Em
When you\’re drunk you\’re terrific
F#m                                 F
When you\’re drunk I like you mostly
Am                                 Em
Late at night, you\’re quite alright
Ebmaj7                 Cm7                 Bbmaj7
But I can\’t understand the different you
Ebmaj7                 Cm                 Cm7        Cm6
In the morning when it\’s time to play
D
At being human for a while
E7
Please smile

[Verse]
F#m                                                 F
You\’ll be different in the spring, I know
Am                                 Em
You\’re a seasonal beast
F#m                 F                 Am                                 Em
Like the starfish that drift in with the tide, with the tide
F#m                 F                 Am                                 Em
So until your blood runs to meet the next full moon
F#m                                 F                 Am                 Em
Your madness fits in nicely with my own, with my own
F#m                 F                                 Am
Your lunacy fits neatly with my own
F                                 Am
My very own
F Am (x5)
F                 D
We\’re not alone
