OVERTURE

So did you hear the story of the Johnstone twins?
As like each other as two new pins
Of one womb, born on the selfsame day

How one was kept and one given away
And did you never hear how the Johnstones died?
Never knowing that they shared one name
Until the day they died
When a mother cried "My own dear sons lie slain".
And did you never hear of the mother
So cruel there was a stone in place of her heart
Then bring her on
And come, judge for yourselves how she came to play this part
