6. FERRIS BUELLER'S DAY OFF
It's not exactly a concert in the strictest sense, but when Ferris Bueller climbs up on a parade float while he's supposed to be laying low playing hooky, you know he means business. He risks getting caught by the whole city of Chicago, just to get his uptight buddy Cameron to crack a smile.

His rendition of the Beatles song "Twist and Shout" gets the whole city moving, even Ferris' father, perched up in his office building. There are women being thrown into the air, crowds of people dancing in unison, and a sea of people consuming the street surrounding the float. If people knew parades like this happened on weekdays, more people would be skipping school.
