I just got back from seeing him doing his spoken word stuff in Newcastle. He's right about literally everything. I mean seriously, not at one single point, for even a millisecond, did a part of me think "Well Henry, that's not strictly true..." or "I see what you're getting at, but...".
I have therefore come to the conclusion that he is either;
a) More persuasive/adept with all that mind-trickery funk than Derren Brown
b) The second coming of Jesus Christ
