"Glee" favorites Lea Michele (Rachel), Cory Monteith (Finn), Amber Riley (Mercedes), Chris Colfer (Kurt), Kevin McHale (Artie), Jenna Ushkowitz (Tina), Mark Salling (Puck), Dianna Agron (Quinn), Naya Rivera (Santana), Heather Morris (Brittany), Harry Shum, Jr. (Mike), Chord Overstreet (Sam) and Darren Criss (Blaine) will be featured in the concerts.

"Glee" creator Ryan Murphy conceived the live event, which will feature songs from both seasons of "Glee," including "Empire State of Mind," "Toxic," "My Life Would Suck Without You," "It’s My Life" and "Don’t Stop Believin'." Previous U.S. concerts featured a set suggesting McKinley High School. 

Murphy also hinted that a second U.S. tour may also be in the works. "We had such a great time putting together last year’s shows and the response from the fans was incredible," he said in a statement. "People around the world want to see our cast live and in person, so this European tour is our way of thanking them for the unbelievable way they’ve embraced our little show. And for everyone in America who has asked if we’ll be back to a city near them this summer, stay tuned. We’ll have some exciting news very soon."

Tour dates include the MEN Arena in Manchester (June 22, 2011), London's O2 Arena (June 25-26, 2011) and Dublin's O2 Arena (July 2-3, 2011).
