Hi Ken!
Please see the lines for the clue below:
Be careful thee who witness dear MacBiden led astray
A victim of fate and fortune cast
To play the role like each man past
For if it's said that something wicked comes this way

That's it! It's meant to be a silly sort of fun detail for him to find. If you could introduce yourself and read the lines in a serious voice I think he'd really love it.
Let me know if you're interested and I hope all is well!
