The University of Iowa appears clueless as the rest of us to the source of nightly playing of the school’s fight song in Niagara Falls, New York -- on loop for seven hours.

The Niagara Gazette first reported on the mysterious music, emanating from the open windows of a vacant building a few blocks from Niagara River and the U.S.-Canadian border. The noise has led to complaints from residents and customers of a nearby restaurant.

The fight song plays without lyrics daily from about 4 to 11 p.m. according to the Gazette. It started six months ago. Attempts by the newspaper to reach the person responsible for the music have been unsuccessful.

Or is it even a person? Perhaps, only a supernatural explanation exists.

The melodious mystery dates roughly to the start of the football season. Iowa rolled to 12 straight victories, a school-record total, and appeared in its first Rose Bowl since 1991. More recently, the Iowa men’s basketball team has climbed to No. 3 in the AP rankings after a 16-3 start and seven straight Big Ten wins.

Iowa spokesman Steve Roe said he was aware of the reports about the fight song.

Wrote Roe in an email: “The Hawkeyes are everywhere!”
