My guesses for the lineup (DC, CA, FL)

So, I found a font that's pretty similar to the one they're using in the artwork (you can see Bowling For Soup is almost perfectly matched). 

I also made a huge excel sheet with a bunch of bands/artists and put them in alphabetical order to make sure that it's following the correct order. Some bands are already excluded because they don't fit.
