It's a Sin歌词：
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
