BFA friend Greg Witul passed along this ad for a Polka Festival @ Saint John Cantius Church from 1976. For those who don’t know, Saint John Kanty used to be called Saint John Cantius. I believe the name change came in late 1970s if I recall correctly.
What I don’t have a recollection of is this festival at all…do you remember? Based on the ad, it looks like it was a huge event. The church offered shuttle service from offsite parking areas around the neighborhood.
