Jason Mraz Kicks Off North American Leg of Tour with Christina Perri

Jason Mraz kicked off his Tour Is a Four Letter Word trek back in June overseas, but he's finally bringing the fun to North America starting Thursday night in New Orleans.  As an added bonus, his buddy Christina Perri is along as his opening act.

Jason's tour comes in support of his latest album, Love Is a Four Letter Word, and he says it's a mixed blessing to have so many albums to pull material from when he's making up his tour set list.  "It is difficult," he tells ABC News Radio, "especially because between every song, they're shouting requests, and I know I've only got two and a half hours to play music and I've got way too much music now for that."
