This week on A Prairie Home Companion, we'll visit the majestic open air Greek Theatre in Los Angeles, where the no smoking policy is now enforced with high-pressure water cannons and helicopters loaded with foam. With us this week are piano man Randy Newman, the California kid Martin Sheen, comedienne Paula Poundstone, and cellist Meta Weiss. Also with us, the Royal Academy of Radio Acting: Tim Russell, Sue Scott, Fred Newman, and Erica Rhodes, The Guy's All-Star Shoe Band with Richard Dworsky, The News From Lake Wobegon, and much more, coming up this week on A Prairie Home Companion.
