We walk together on a Monday, a special programme today to commemorate 9/11, the date in September that changed the course of history forever, socially and geopolitically. The commemoration includes archive interview material with photographer Joel Meyerowitz and photojournalist Jason Florio, with previously unpublished thoughts from the New York City-based street photographer Phil Penman. This programme contains material and language that some listeners may find disturbing. Links to all stories and guests will be on the SHOW PAGE) as always and my sincere thanks to mpb.com) who sponsor this show and the Extra Milers) without whom we wouldn't be walking every week.
