Pre-sale and general ticket-sale information for the newly added dates will be available at The Wiggles' website beginning Monday (7/16). The group performs afternoon and evening shows in most cities.

The Wiggles, who hail from Australia, have been performing live for 16 years. Their latest album, "Racing to the Rainbow," is the latest addition to a huge catalog of music, television, video and film projects that have earned the group a slew of awards, wide critical acclaim, and a devoted fanbase of youngsters who sing and dance in the aisles.

Next up is "The Wiggles: Getting Strong!" DVD, which will be released in October as part of the group's new distribution deal with Warner Home Video.

The DVD will be the first with the new Yellow Wiggle, Sam Moran, who replaced band co-founder Greg Page late last year. Page was forced to retire because of a health condition that causes problems with walking, balance, speech and coordination.

The Wiggles have sold more than 15 million DVDs and videos in the US, more than 2.5 million albums and more than 7 million books, according to a press release. The four Wiggles, in their distinctive colored skivvies, are joined on stage by special guests Dorothy the Dinosaur, Wags the Dog, Henry the Octopus and Captain Feathersword for more than 150 shows a year in front of 750,000 fans.

The franchise has grown to include Taiwanese and Spanish-speaking versions in addition to amusement parks in the US and Australia.
