Pretty sure fiscally minded Brian would set aside political beliefs to do his job and keep living his lifestyle (or Leighanne's, whatever, lol). If countries are requiring it for entry, it absolutely seems like a no-brainer for the Boys, especially since live events are the vast majority of what they earn money from these days what with earnings from albums being increasingly minuscule in a digital world and most of any licensing residuals going to people like Max Martin instead of the Boys.
Heck, maybe Kevin kidnapped him and dragged him to a Walgreen's or something while they were all in LA, lol.
Regardless, stay positive! The tour's not for another year anyway!
(We're keeping positive thoughts over here in Dee land that all is well in a year.)
