Factual error: In the scene when ADD is first leaving to go on tour, they drive past the Rock and Roll Hall of Fame and the bus driver announces, "On your left..." The shot of the museum as they drive by is the front. The road going by this way dead ends; there would be no way for them to get on the highway or a surface road. (Look on Google Maps. They are on East 9th Street going northwest.)
Factual error: In the movie, A.D.D. is opening for Vesuvius' induction into the Rock and Roll Hall of Fame, after Vesuvius becoming famous 20 years ago. This is an error because you have to be famous for 25 years to be inducted, not 20.
