@Nyctophilia Never been to a concert on my own. Would like to though. Have done other things on my own fine that most people won't (solo travel I do a lot).
London I'm used to at this point. But yeah, not sure I'd want to be going from O2 to the rail stations on the tube, then a train back out of London at the time concerts usually end?
I'm wondering if it is the visa process that means the US and Canada get to go last. Quite a few European countries have music touring as permitted work on a visa waiver, but far as I'm aware, that isn't the case if you go the US or Canada on a waiver. Which means paying for visas for band + crew, then playing the waiting game. Do hear that getting a US visa is a bureaucratic nightmare that takes a long time.
