Just read on some Australian sources, that a new book on Ken Rosewall is out, with the title "Muscles". Its published by Richard Naughton, and obviously has contributions by players like Laver and Newcombe and famous writers like Bellamy and Barrett. Maybe some here like Bobby one know more about it. I haven't seen an announcement here. Could be a very interesting read. Forgive me. I made an error in the title line and cannot edit it.
