—And Rhymefest. I-I—Let me talk for myself.

You'll also hear the never-before-released rap—

Hold on, hold on! Don't tell 'em what's getting ready to happen. Just—Just bring Mike in, man. Let—Let's do it. Let's do it.

Okay, tape's rolling. A-A-Any time you want.

Hahaha. You crazy, Mike. You do it all low: "The Thriller…"

Do we both say it?

I—Do we say it together, or—Do we say, "It's the Thriller," or "I'm the Thriller?"

Anytime. Tape's rolling
