Shakespeare  is visited by a history of Scotland

telling how that wily dame urged on the Thane,

impressed by a chant of three wise women.

Witchcraft convinces the Lady.

She calls Macbeth a coward,

instills in him murder, murder,

overthrowing another king, to

become the head of the realm.

The tale is one of blood and deceit,

killing is what they do because they

cannot do otherwise.

Dread replaces sleep.

A lot more blood, and there is sleepwalking, singing,

overacting, and high notes in the opera.

Finally there is death and blood,

Lady Macbeth dreams the dream.
