Backup (intro):
And that was the biggest sin of all
Connie:
It was a sin the way you lied to me
The way you broke my heart
But that was not the biggest sin of all
It was a sin the way you made me cry
And vowed we'd never part
But that was not the biggest sin of all
You promised to be faithful
And I trusted in you
Oh, what a sin
You just couldn't be true
But the biggest sin of all
Was when you made believe you were mine
When there was somebody else
All the time
(spoken)
I should have known you didn't love me
With all those lied that you told
And I should've known
That there was another
When your kisses were so cold
Yes, I closed my eyes
Too much in love to see
Oh, why, did this ever have to happen
To me
(reprise)
Yes, the biggest sin of all
Was when you made believe you were mine
When there was somebody else
All the time
