An average of 30 people are competing for each seat available for the remaining live broadcasts of Garrison Keillor’s “A Prairie Home Companion� radio show, which ends June 13. “People are calling from out of town, like New Jersey, a lot of people from the South, and are ready to drop everything and come up here for the show. People are willing to change their vacation plans to see the show,� said Marilyn Schultz, director of the 77-year-old World Theater in St. Paul, Minn., where the show is broadcast nationally on Saturday nights by Minnesota Public Radio. In the first week after Keillor announced Feb. 14 that he was quitting the show, 22,000 phone calls poured in, she said.
