text: DANCING WITH THE STARS - "Episode 2106" - The remaining nine celebrities returned to their original professional dance partners to tackle "Famous Dances Night" on MONDAY, OCTOBER 19 (8:00-10:01 p.m., ET) on ABC's "Dancing with the Stars." Special guest Olivia Newton-John joined the judges' desk to see how the couples re-created iconic dance routines from movies and music videos. One couple was eliminated at the end of the night based on the lowest combined judges' scores and viewer's votes from the "Switch Up" and "Most Memorable Year" performances.
