Don't have twitter myself, but we should ask Daniel Johnston.
then make an account, it takes seconds and its probably better if you dont have an account, I have to care about pissing off friends by spaming their feeds with tons of tweets asking people if they will be at bonnaroo
Asked Japandroids management if they were playing because it would have an affect on if I book my trip to roo (85% true) this was the response I got: "I can't tell you whether Japandroids are playing Bonnaroo or not, but you should just book your trip." to me thats pretty much a confirmation Id think. Also supports my thoery for them as roo clue #1
