One of the guests that will be featured on Shania Twain's upcoming CBS television special on March 3rd will be Elton John. The two recently performed a trio of numbers together, including Twain's "'You're Still the One" hit. The one hour special (reportedly, similar to Celine Dion's holiday special) will feature interview segments, hit performances and other duets with surprise guests. Additionally, Twain was recently a winner at the recent American Music Awards and graces the cover of the February issue of Cosmopolitan magazine.
