Strangely enough, while I am an avid reader of non-fiction, biographies/autobiographies are one of my least favourite subjects. I have a number of biographies about the composer Frederick Delius (I find him a fascinating individual), but other than that, I have read very few. As far as speedway goes, the only ones I have read are Briggo (the original), Kenny Carter, Tommy Jansson, and Chum Taylor.
