John McCane is a multi-instrumentalist with a multi-faceted auto-immune disease known as Wegener’s Granulomatosis, a form of vasculitis (did I lose you yet?). In this episode of Friends With Deficits, John describes the fascinating, frightening, and sometimes just gross details of his symptoms, diagnosis, and treatment, along with an intriguing possible cause.

He also performs some rad, old-school beatboxing and a couple little instrumental compositions to round out the story.
