As the title suggests this is probably going to be a really dumb question but are those guys who were touring with dallas now in the band permanantley? yes i realise i cant spell haha

No. They play in a band called Attack in Black..although they since Attack in Black is supporting City and Colour on a lot of his tour you'll probably see them on stage during his set too.
