A Cauldron of Creeps

I am Lestat the vampire & I have a history of singing
at inappropriate times. I've tried everything to stop,
short of slitting my own throat.

It started in Miami in 1990 & my intention at the
time was to start singing and then stop. But it's
important to understand that while I'm sleeping I
do not have control over my interior dialogue and I
sometimes start singing uncontrollably. I've tried
refried beans, I've triedVampire Chili and, God help
me, I've tried Robitussin®. And if any of you repeat
this I swear on my mortal friend David Talbot that
I will haunt any function you're inhabiting by
breaking into an acapella version of "Me & My
Shadow".
