Bon Jovi started the stadium leg of the 2010 Circle Tour by playing the inaugural show at the
New Meadowlands Stadium in East Rutherford, New Jersey. Three sold-out shows on May 26, 27, and 29 prompted the addition of another tour date at the venue at the start of the second North American leg on July 9. The band played a free performance for fans and former season ticket holders of the
Jon Bon Jovi-owned arena football team The
Philadelphia Soul on March 24, a few hours before the band's show at Philadelphia's
Wachovia Center. On June 7 they became the first band to play on the roof of the O2 Arena in
London, England. The performance was shown outside on a large screen with a PA system. Trained mountaineers helped the group to reach the top of the roof, which was 58 meters above the ground. The tour featured a circle-shaped stage with five large robots, choreographed to move with the music and onstage production, which each had a 6' by 9' Nocturne/ Vidicon LED screen attached to their articulated arms. They were provided by RoboScreen and designed by
Andy Flessas. ==Opening acts==
