Lady Scotch that Snake

Fanny—
I guess you wonder why I'm here
Togged up like Lady Gwinevere
But control your desire to curse
Or I'll sing you something worse
The tale I'll tell you you've heard before
'Bout a worthy Scottish thane to whom I'm squaw
I'm a nasty bit of work
And I got myself tangled up with a jerk
A guy named McBeth
Mixed up in a death
Who said that crime don't pay
Take it away!

That which made them drunk hath made me bold
It's a royal session and I won't be told
It's adversity, it's calamity, it's catastrophe!

The multitudinous seas incarnadine
But I hear a knocking somewhere down the line
At the west gate, at the east gate, at the south gate.

Most times like this I have a side kick who'll do all the work
But for this job the guy decided to shirk
If you've ever heard alarms of the Royal Duncan and the Thane of Glamis
It's a mystery, it's a history
It's a flagrant tale of a vagrant male
It's disruption, it's destruction
Of an escutcheon.
