To Geoff the Duck

Yes, I have been known as Arbuthnot Thrope, Perfect Pitch Percy, and Blind Orange Peeler. My schizophrenia has now extended to the point where I do (operative word) folk evenings in three half-hour spots as Rambling Craig Rumpo (the historic folk singer), Steel Rail Craig (Robert Johnson's buddy), and C. Lee Farquhar (nuff sed). I am also in a blues band called Boffa, with three other people who think they are sane. Who the blazes are you?
