Negative blues [English translation]

Where is my girlfriend ?

She is in my Rolleiflex 1

I look at it puzzled

Must I chuck it in the nettles 2

Where is my girlfriend ?

She is in my Rolleiflex

It was my first reflex 3

I like photography

I see the little darling again

Posing for my Rolleiflex

A little thing in Lastex 4

Gave her a bit of spirit

Where is my girlfriend ?

She is in my Rolleiflex

I gave her a few complexes

She ran away that night

Where is my girlfriend ?

She is in my Rolleiflex
