How can I watch ? The show begins at 8 p.m. Eastern Time on CBS and is expected to run three hours. James Corden — a theater fan from way back — will be the host for the second time. Among those slated to appear at the Radio City Music Hall ceremony: the pop singers Cher, Josh Groban and David Byrne; the film and television stars Tina Fey, Danai Gurira and Jake Gyllenhaal; and theater favorites Kristin Chenoweth and Audra McDonald.
