Given that somehow over the course of the past few years, the Glee Cast have become one of the most successful recording acts in Billboard history, it was probably somewhat overdue for the group to have a full-on, nationwide arena tour. The show cast's "Glee! Live! In Concert!" tour now encompasses 18 dates, starting at the Mandalay Bay Event Center in Las Vegas on May 21, and continuing cross-country to its final stop on June 18 at the Nassau Coliseum in New York. The concert event, which already featured the great majority of the show's cast (including stars Cory Monteith and Lea Michele), also recently added Ashley Fink (Lauren Zizes) and a number of the ever-popular Warblers group as well.

Meanwhile, the Warblers appeared on the Today Show earlier today to promote their new album, performing their rendition of "Hey Soul Sister." It's a largely lip-synced performance (outside of Darren Criss's shaky lead vocal), and it's of one of the worst songs in music history, but if you wanted to watch it anyway, we won't stop you or anything.
