Bb F/A Eb I press on the elastic sheet, I'm breathing through a slice G Bb Dd B 'Are they worms or are the serpents?' bubbled through the ice

Ab/C B G/B F

The source was quite invisible, the ever-present voice  A/E E B Bb While skating, both legs tracing different shapes, I made my choice

Next vers has the same chords, except that just before going to a chorus, the last chord is an E instead of a Bb.

Chorus:

G D

He's fallen on the ice it cracks

Dm7 C

Will he plunge in and join me here?

G D

Meets my eyes to my suprise

F D

Laughs the full light of my frown

My double wants to pull me down

E

 E Eb D Db Bb A Ab G
