Executives at the O2 announced that the four concerts that took place over the June 25-26 weekend brought in over 66,000 fans. The cast of the hit Fox television series received a special honor to commemorate their achievement.

The European tour of "Glee Live! In Concert!" launched June 22 in Manchester, England and played the final leg of its European mini-tour July 2-3 at Dublin's O2 Arena.

"Taking our show across the Atlantic and performing at The O2 has been a dream come true for all of us, and the incredible reception we got when we arrived was more than we'd ever imagined," said Glee executive producer and co-creator Ryan Murphy in a statement. "We cannot express our gratitude for the outpouring of love and enthusiasm we have received. It truly has taken our breath away."

The tour featured Lea Michele (Rachel), Corey 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).

As previously reported, Twentieth Century Fox Television and Twentieth Century Fox Film have partnered to present "Glee Live! 3D!," a film of the U.S. summer concert tour, which will play a limited two-week release in cinemas worldwide beginning Aug. 12. Kevin Tancharoen, who directed the remake of the hit film "Fame," will direct.
