Since the mid-1980s, changes have taken place inside Glasgow's football strongholds, Celtic and Rangers. From the signing of a Catholic and the arrival of top English stars at Ibrox Park, to virtual civil war at Parkhead which made way for Fergus McCann to take control, this book asks if money has taken over from the raw passion of another age, and considers what has happened to the "business based on bigotry" that was for so long at the core of the Old Firm.
