It's the Spring Pledge Drive, so we offer up a *Sound Affects Sampler*, with examples of many of the kind of things that you might hear on Sound Affects. Guests in the studio are comedian Dean Johnson and playwright David O'Sullivan. Short tidbits from the Firesign Theatre, the Borgus Collective, Great Northern Audio and more, including music played by President Harry Truman. We also mention the upcoming live radio drama broadcast at the Pavek Museum in St. Louis Park, MN this coming Sunday, April 3 at 4:00 PM.
