After 40-plus years of delighting radio audiences each Saturday night with America’s favorite live variety show, A Prairie Home Companion founder and host Garrison Keillor bids farewell with an unforgettable performance in the Hollywood Dish in Los Angeles, California. It’s a duet performing extravaganza, with Sara Watkins, Sarah Jarosz, Aoife O’Donovan, Heather Masse, and Christine DiGiallonardo joining Garrison on time-honored American ballads, English Invasion romps, country-western weepers, and Broadway classics. Plus: The Royal Academy of Radio Stars, Tim Russell, Sue Scott, and Fred Newman, with L.A. stories and sound files straight from hurry hour within the 101; Music Director and pianist Richard Dworsky goes wondrously from stride and spirituals through browse instrumentals and a bit of Rock n Roll; a particular sendoff from Chief executive Barack Obama; and one last revise on the news headlines from Lake Wobegon, the tiny town that time forgot, and the years cannot improve.
