After a falling out, James Bolam and Rodney Bewes did not speak to each other for nearly 40 years. However, following Rodney Bewes death, Bolam claimed there had been no falling out and they had simply gone their seperate ways and were never close friends, just colleagues who worked together.
Despite the fact they had had no contact for several years, it would seem unlikely they would not have recognised each other in the train carriage.
