The Dalton Academy all-boys a capella choir hit the talk show's live stage in promotion of their new studio release, 'Glee: The Music Presents the Warblers,' which features 11 of the Warblers' most popular covers including Destiny Child's 'Bills, Bills, Bills' and P!nk's 'Raise Your Glass.'
Heartthrob lead singer Darren Criss, who plays Warbler frontman Blaine on the show, sat down to chat with Ellen after the performance about everything from performing on stage with Katy Perry herself to the upcoming 'Glee' summer tour. He even gifted the talk show host her very own Dalton Academy blazer.
Criss' appearance on 'Ellen' follows the recent announcement that he will pursue a solo career and release his own album with Sony. Criss and the Warblers are making the talk show rounds -- the singing group also appeared on the 'Today' show earlier this month.
Watch the Warblers perform Katy Perry's 'Teenage Dream' on 'Ellen.'
