Argentina. The tour included cities in the United States, Canada, the Caribbean, Mexico, Central America and South America. The brothers were accompanied by Demi Lovato and the cast of Camp Rock 2: The Final Jam to promote their albums Here We Go Again and Camp Rock 2: The Final Jam respectively. Background While announcing Nick Jonas' side-project Nick Jonas and the Administration, the Jonas Brothers announced they were planning a world tour to take place during the summer of 2010. On April 27, 2010, the band and Lovato officially announced the tour, through their official websites and MySpace pages. The tour featured the band with special guests Lovato and their friends and co-stars from Camp Rock and Camp Rock 2: The Final Jam. The tour included both songs by the band and songs from the films. The pop group Savvy performed as a supporting act on select dates. The brothers set list also included songs from the soundtrack to their Disney Channel Original Series, Jonas. The tour began on August 7, 2010, in Illinois. It was originally supposed to begin on July 27, 2010, in Dallas, but was moved back, due to changes in their schedule.

This concert was not in the round and played mostly in amphitheaters across the country and around the world. Some of these tour dates have been canceled and changed. The tour started on August 6, 2010, two weeks later than planned, which allowed Nick Jonas to perform in the West End production of Les Misérables as Marius Pontmercy in London. The Tampa, Florida tour was cancelled due to flash flooding at Tampa's 1-800-ASK-GARY Amphitheater. The San Nicolás, Mexico tour was also cancelled. Both shows were not rescheduled.

After Lovato left, they were interned in a treatment center to seek out help and the tour continued without them until its last show.
