The Factory Whistle Concert will again fill the early Christmas morning air in York at 12:15 a.m. on Sunday, Dec. 25. Whistle maestro Don Ryan and his son, Scott, will present the 25-minute concert using the variable-pitched whistle now installed at 240 Arch St., York. Practice concerts are scheduled at noon on Saturdays, Dec. 17 and 24.

Ryan will celebrate his 68th anniversary performing this one-of-a-kind concert. It will also be at least 134 years that a whistle has been played in York on Christmas Eve. The whistle can easily be heard within a 5-mile radius of the concert location, and depending upon the wind, the whistle has been reported from as far away as 10 miles.

For the eighth year in the concert's history, people from around the world will be able to view the concert by visiting http://www.yorkpafactorywhistle.com or searching for "Factory Whistle" on Facebook. The Factory Whistle Master app is also available for downloading. Streaming will begin at midnight.

The concert has numerous sponsors and is supported through donations from community businesses and residents.
