"When I look back upon my life
It’s always with a sense of shame
I’ve always been the one to blame
For everything I long to do
No matter when or where or who
Has one thing in common, too

It’s a, it’s a, it’s a, it’s a sin
It’s a sin
Everything I’ve ever done
Everything I ever do
Every place I’ve ever been
Everywhere I’m going to
It’s a sin

At school they taught me how to be
So pure in thought and word and deed
They didn’t quite succeed
For everything I long to do
No matter when or where or who
Has one thing in common, too

It’s a, it’s a, it’s a, it’s a sin
It’s a sin
Everything I’ve ever done
Everything I ever do
Every place I’ve ever been
Everywhere I’m going to
It’s a sin

Father, forgive me, I tried not to do it
Turned over a new leaf, then tore right through it
Whatever you taught me, I didn’t believe it
Father, you fought me, ’cause I didn’t care
And I still don’t understand

So I look back upon my life
Forever with a sense of shame
I’ve always been the one to blame
For everything I long to do
No matter when or where or who
Has one thing in common, too

It’s a, it’s a, it’s a, it’s a sin
It’s a sin
Everything I’ve ever done
Everything I ever do
Every place I’ve ever been
Everywhere I’m going to - it’s a sin
It’s a, it’s a, it’s a, it’s a sin
It’s a, it’s a, it’s a, it’s a sin

(confiteor deo omnipotenti vobis fratres, quia peccavi nimis cogitatione,
Verbo, opere et omissione, mea culpa, mea culpa, mea maxima culpa)
[trans. i confess to almighty god,
And to you my brothers,
That I have sinned exceedingly
In thought, word, act and omission,
Through my fault, through my fault,
Through my most grievous fault]

(zero!)"
