CAUGHT IN THE ACT | Can GARRISON KEILLOR ever step out of character? Possessor of one of the most recognizable voices in radio, the entertainer and humorist leaves aside his Prairie Home Companion duties for a solo show of stories and anecdotes, with special attention to his insights about “late-life fatherhood.” Like Stephen Colbert, Ellen DeGeneres, or Ted Nugent, Keillor’s hit the point of celebrity where his life is simply playing a persona with the same name. He hits the Collins Center for the Arts at the University of Maine in Orono at 7:30. Tickets range from $48-78. 207.581.1755.
