Elton John [ tickets ] has firmed up his schedule through October for "The Red Piano," his two-year-old Las Vegas production.

About two-dozen new shows have been announced for July and October. As previously reported, John's next stint of Vegas dates is set to get underway March 28. Tickets for all confirmed shows are on sale now.

"The Red Piano"--a production created by John with photographer David LaChapelle to spotlight the songs of John and longtime writing partner Bernie Taupin--made its debut at The Colosseum at Caesars Palace in 2004. John's initial agreement with Caesars called for 75 shows over three years, but the production proved to be a hot seller, prompting the resort to book John for more than the initially planned 25 shows per year.

Last year, the singer/pianist signed a new agreement that calls for an additional 150 shows through 2008, according to Caesars.

The Colosseum is a 4,100-seat theater originally designed to host Celine Dion's production, "... A New Day." "The Red Piano," plays on select nights when Dion is off.
