A free-lance writer and teacher working on an unauthorized biography of “Lake Wobegon Days” author Garrison Keillor says he’s having problems gathering material. Michael Fedo, 47, who lives near Anoka, Minn., where Keillor grew up, told AP that he’s been hampered by refusals to comment from Keillor and people who are important to the life and career of the host of American Public Radio’s popular “A Prairie Home Companion.” Keillor could not be reached for comment. Fedo said he is writing the book for St. Martin’s Press in New York and has received an advance of between $5,000 and $8,000.
