It was the dance that brought everyone to tears, then to their feet.
Iraq war hero J.R. Martinez paid tribute to fallen soldiers in what was perhaps the most emotional moment ever on Dancing with the Stars.
Martinez collapsed into partner Karina Smirnoff's arms after the dance.
The studio audience which included an injured war veteran gave Martinez a standing ovation.
"I have the opportunity to be a voice to all those men and women, to those families, that mourn the loss of a loved one in the war," said Martinez.
Chaz Bono began his dance with a kiss to his late father Sonny Bono. He did his rumba to one of Sonny's classic songs.
"I think he would have loved it," said Bono.
Mom Cher watched from home, tweeting: "God hope Chaz hangs on till next week so I can come sit in the Audience & Watch."
"She's been so supportive all along. I think it would be great to see her sitting in the audience," said Bono.
"I would be very excited," said Lacey Schwimmer.
