When Vesuvius' manager is informing Fish that he is fired from the band, The song "Nobody's Fool" by _Cinderella (IV)_ is playing in the background, specifically the lyric can be heard over the scene: "seems like a thousand years since we broke the ties."
Some of the scenes were filmed in Toronto, Canada (not actually Ohio). The Chinatown scene was filmed on Spadina street in Toronto's Asian district. One of the earliest club scenes when they exit the gig and into a back alley to a limo, was filmed in and outside an all ages club downtown called the Reverb.
After Aziz has taken off the plastic wrapping of his new bought Vesuvius CD, he takes it out the box and holds it up with the back facing the camera - The CD is clearly a CD-R with a green recordable back, not a silver backing like any original store bought audio CD would have.
Vesuvius is slated to be inducted into the Rock and Roll Hall of Fame after 20 years together. However, artists aren't eligible for induction (barring an extenuating circumstance) until 25 years have passed since the artist released his/her/their debut.
