"P. Diddy & MTV Present Making the Band [ tickets ] 4 - The Tour" has been re-routed due to scheduling conflicts, according to organizers, causing cancellations throughout the United States.

Details are listed below and ticket refunds are available at point of purchase. The tour will include performances by chart-toppers Danity Kane [ tickets ] and Day26 [ tickets ], as well as newcomers Donnie Klang [ tickets ] and Cheri Dennis [ tickets ].

Danity Kane's "Welcome to the Dollhouse" marked the group's second consecutive No. 1 chart entry, following its 2006 platinum-certified, self-titled debut. The feat marks the first time an all-female group has topped the main album chart with its debut and sophomore sets, according to a press release. The new album's lead single, "Damaged," hit the No. 1 spot on MTV.

Day26 sold more than 190,000 copies of its self-titled album during the first week of release, making the set the biggest-selling debut from a male R&B group in the 17-year history of SoundScan, according to a press release. The record features the current hit, "Got Me Going," and upcoming single "Since You Been Gone."

Klang, who has 3.6 million page views on his MySpace page, is using the tour to support his debut album "Just a Rolling Stone," due to hit stores Aug. 19. He compares his album to those by Prince and Michael Jackson.

"I've had my heart broken before," Klang said. "I expected to go and sing these songs that I could just rub in my ex-girlfriend's face. But we just came out with songs that were just sick--like Prince and Michael Jackson. They were singing about basically nothing, but the songs were hot. They were sexy songs. They're on that vibe. It's some new age '80s type of stuff."

Klang appeared on MTV's "Making the Band" but he didn't make the cut as a band member. Instead, P. Diddy signed him to a solo contract. He explained that working with P.Diddy was "definitely tough."

"The first season when we were auditioning, basically he was looking down at his BlackBerry and we're all standing there singing our butts off trying to get into the group and he's not making eye contact with us," Klang said. "Then there's this one day when he looks up or kind of smirks and you're like, 'Oh my God. I got his attention.'"
