Imus' guest list hasn't been determined yet, but he will interview someone about the Civil War, said Manning.
"He's certainly got a large following and to focus the attention of that program on Washington County, the Maryland Theatre and Antietam certainly is a boost to our area - a promotional boost," Manning said.
The I-man's visit will be a better promotional boost for the area than the Tour DuPont bicycle race that used to whiz through the area annually, he said.
"He's on in over 100 radio markets," said Manning. Oldies 106.9 and WARK 1490 have been affiliates of the "Imus in the Morning" program for four years, making the stations one of the program's first affiliates since it became syndicated, Manning said.
Imus has been a leading New York radio morning man since 1971, according to the radio station's web site at (http://www.warx.com).
The program usually originates from WFAN in New York, but occasionally Imus goes on the road with his band of sidekicks, including Rob Bartlett, who does voice impressions, Manning said.
Most of the tickets to the show will be taken up by corporate sponsors and their guests, but about 600 tickets will be available to the public for balcony seats, Manning said.
Manning said he expected the $25 tickets to go on sale next week through the theater's box office.
Several tickets will be given away on-air to listeners of the two radio stations, he said.
Sponsors include Farmers & Merchants Bank and Trust, Legg Mason and Don Phillips Jeep Eagle in Frederick, Manning said.
Proceeds from tickets sold to the public will be donated to United Way, Easter Seals and the Maryland Theatre.
