From Yahoo! TV 8/19/05 For the whole article: http://tv.yahoo.com/news/eo/20050818/112442130000.html And so the dance-off: The Monaco and O'Hurley teams will compete in Latin, ballroom and freestyle. The 90-minute special will be filled out with "dance demonstrations" by: Ashly Delgrosso, Joey McIntyre's former partner; Jonathan Roberts, Rachel Hunter's ringer; Edyta Sliwinska, survivor of Evander Holyfield's moves; and, Louis van Amstel, Trista Sutter's harsh taskmaster. Kelly Monaco and John O'Hurley will return to the Dancing with the Stars ballroom for a so-called "dance-off" on Sept. 20, ABC announced Thursday. The results, based solely on viewer voting, will be announced in a Sept. 22 telecast. The results show, airing two nights later, will be kept to a relatively spare 30 minutes.
