The band performed in downtown Pittsburgh on Friday.
The lunch crowd in Market Square were in for quite a surprise when the Riverview High School marching band began performing Friday afternoon. The band organized a flash mob in the middle of downtown, performing The Beatles hit "Hey Jude" and Psy's "Gangnam Style." Seniors also went along for the ride to support the band. This is the band's second flash mob—the first occurred when a local band competition was canceled earlier this school year. Did you see the band?Take pictures?
