Long before he lurked in a dark parking garage as “Deep Throat” in the film All the President’s Men, actor Hal Holbrook was a college student who created his one-man show Mark Twain Tonight! for an assignment. Almost 60 years later, he’s performed the show around 2,200 times and counting, earning a Tony Award along the way. (Presented by Lobero Live, 11/10, 8pm @ Lobero Theatre)
