The thought of people in this day and age sitting down to listen to a radio variety show on Saturday evening is rather implausible and was even more so in 1974 when we started “A Prairie Home Companion.” Thank goodness Minnesota Public Radio was too poor to afford good advice or the show never would've got on the air. We only did it because we knew it would be fun to do. It was a dumb idea. I wish I knew how to be that dumb again.
