The cast of “A Prairie Home Companion” reunites for a Christmas show all about coming together during these politically divisive times. The Royal Academy of Actors, Tim Russell and Sue Scott, join with the Guy’s All-Star Shoe Band, sound effects wizard Fred Newman, writer/host Garrison Keillor, and vocalist Heather Masse to bring you the show you’ve been missing on your radio dial ever since Keillor’s retirement in 2016. Expect witty scripts, parody songs, sweet duets, and of course, the latest News from Lake Wobegon.
