Pitch Publishing author Alex Daley was the subject of the latest TKO Radio boxing podcast, talking about his book Fighting Men of London, and the unique historical era in which it is set.
Fighting Men of London explores the lives of seven former professional boxers who fought in the capital between the 1930s and 1960s.
Its subjects include 1950s boxing star Sammy McCarthy, Bethnal Green knockout specialist Ted Berry (an associate of the notorious Kray twins) and Sid Nathan, one of Britain's last surviving pre-war pro boxers.
