British comedian James Corden is the host of “The Late Late Show.” A regular feature on his show is “Carpool Karaoke.” It shows Corden and a famous person driving around in a car talking and singing along to songs on the radio. Usually, Corden and his celebrity guest are driving around in Los Angeles, where his show is filmed. Many of Corden’s past guests have been famous singers themselves, including Stevie Wonder, Justin Bieber, and Adele. But, this week, Corden “Carpool Karaoke” headed east to Washington, DC. His guest was not a famous singer. But, she sure can carry a tune. This week’s guest was First Lady Michelle Obama. The 15-minute video shows Corden and the First Lady driving around the White House grounds. They sing some of Obama’s favorite songs, including Stevie Wonder’s “Signed Sealed Delivered I’m Yours” and Beyonce’s “Single Ladies.”
