Why are U.S. generals on foreign governments' payrolls?; History of live music

After only 45 days in office, UK Prime Minister Liz Truss resigned, making her the shortest-serving leader in British history. After former Prime Minister Boris Johnson's abrupt departure is instability the new norm in British politics? King's College London Politics Professor Anand Menon joins us. Then, some retired former U.S. military generals appear on the payrolls of foreign governments. They're being paid to provide their military expertise, and some question how ethics, oversight and national security factor into the issue. Washington Post investigative reporter Craig Whitlock joins us. And, live music is more than just artists playing instruments in front of an audience. It also has a rich history in the U.S. as a major business venture. Steve Waksman, music professor at Smith College and author of "Live Music in America: A History from Jenny Lind to Beyoncé" joins us to discuss both its cultural and business significance.
