In less than 18 months, James Corden has gone from “who?†to America’s favorite karaoke singer, and now he’s capped his ascent with a gig hosting this year’s Tony Awards, which, like Corden’s Late Late Show, will be broadcast on CBS. Corden is a past Tony winner, for Best Actor in a Play in 2012, for his role in One Man, Two Guvnors. He is also British, which means that if he doesn’t come out dressed as King George III from Hamilton, we should all ask for our money back.
