A Sin lyrics

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. At school they taught me how to be So pure in thought and word and deed They didn't quite succeed So i look back upon my life For ever with a sense of shame I've always been the one to blame It's a... It's a... It's a... It's a sin.
