CHICAGO (CBS) — If you’re looking for some cheap entertainment for dad this Father’s Day, there are scores of mini-concerts going on all over Chicago today.

People walking through the north end of Millennium Park late Sunday morning were treated to Sousapalooza, a play-along of John Phillip Sousa’s marches by members of the Navy Band Great Lakes and amateur musicians.

They were directed by Concordia University Conductor Richard Fischer, who says the experience is like one big rehearsal concert and is all about making music from the heart.

The performance was one of roughly 200 today in 80 different locations in the city – at places like the Lincoln Park Zoo, the Chicago Cultural Center and the Riverwalk.
