having seen Jeff Daniels on Stephen Colbert's show last night, I'm a bit concerned. His voice sounded quite raspy. He didn't make any mention of being ill, but I sure hope he & his voice are in good shape for tonight's show.
In other late night talk show news, Trevor Noah of The Daily Show lost his voice over the weekend at the Globalfest concert in South Africa and has been sitting behind his desk nightly while different correspondents read his lines for him & conduct interviews. This seems a unique way to handle the loss of voice.
