Stuart Timmons is a personal friend. When The Trouble With Harry Hay was published, Stuart as biographer and Harry Hay as subject jointly signed the book at a bookstore event.
Stuart talked about and signed Gay L.A. at a get-together of our book discussion group. Stuart has attended the group irregularly. On this occasion, he brought a laptop computer and narrated a slide show about some of the stories in the book.
(Note: Years later, I got the co-author's autograph as well.)
