JAMESTOWN, Pa. — Northwestern Pennsylvania fire officials said fog being made for a music video prompted a restaurant to report a fire.

The video was being shot last Saturday afternoon at a teen dance club in the basement of a 19th century building in Jamestown. A restaurant on the third floor was hosting a 70th wedding anniversary party for a couple in their 90s.

Jamestown Assistant Fire Chief Tom Luckock said people at the restaurant called the fire department when the man-made fog filled the building. Firefighters determined it was innocuous.

The businesses are located about 75 miles northwest of Pittsburgh in a building called Mark Twain Manor. The building is named for Twain because he was friends with the physician who constructed the home in the mid-1800s.
