Mark Lawson talks to Sir Bob Geldof about his life and career. From the formation of the Boomtown Rats in the mid 1970s to his work with Band Aid and Live Aid in the 1980s and his continuing influence on key figures on the world stage, Geldof has been a key figure in music and politics over several decades. In 2013, the Boomtown Rats reunited for the first time in over 25 years and Geldof talks candidly to Mark about his career in music, his activism, his family and his very public personal traumas.
