X=Z
Ten years ago on a ccold, hard night,
Someone was killed by the town hall light,
The people who saw it they all did agree,
That the slayer that ran looked alot like me.

Y=Z
:She walks these hills in a long black veil,
Visits my grave when the night winds wail,
Nobody knows and nobody sees,
Nobody knows but ME.

MORE Y=Z (plus irony):
The judge says,"Son, what is you alliby?
If you were somwheres elde then you won't have to die."
I spoke not a word though it meant my life
I had been in the arms of my BEST FRIEND'S WIFE...

EVEN MOREY=Z
:The scaffold is high and eternity's near,
She stands in the crowd and she sheds not a tear,
But oft times and night when the cold winds moan,
In a long black veil she cries o'er my bones.

Yes, I see what you mean !!!
