Watch Online Free on Watchseries. J.P. McCarthy was an icon of Detroit broadcasting who ruled the radio waves in the Motor City for thirty years. His story is the ultimate local-kid-done-good tale. Working extensively with the McCarthy family and conducting over twenty interviews with J.P.’s friends, family, co-workers and contemporaries, Detroit Public Television memorializes someone who was considered more of a family member than a voice on the radio to anyone who tuned in to hear his morning show or the Focus program over the years.
