LBC likes to tell us it’s ‘Leading Britain’s Conversation’, though in the case of weekday pre-lunch presenter James O’Brien you’ll have to sit through a series of bombastic monologues from the host before any punters get a word in edgeways. O’Brien knows everything, and he doesn’t mind telling you. Still, I understand that running a talk show is no job for timid introverts who might burst into tears if callers start giving them a hard time.
