In a surprise twist, Yamaguchi and troop member Sasha Farber joined Hamill and [Henry] Byalikov, subbing for an injured MacManus (broken toe), for the second part of the dance.
"It was a lot of fun -- not just to be back but obviously to dance with Dorothy," said Yamaguchi, the DWTS season six champion. "It was a special moment to share with her."
Byalikov, who collaborated with MacManus on the choreography, was blown away by Hamill's dance abilities. The idea of the dance was to create a piece that included elements of dances Hamill would have performed had she remained in the competition.
"We had a fusion of tango, foxtrot, waltz, rumba, samba and Argentine tango," Byalikov said. "She took it in stride. ... It's not easy to have that type of versatility, but she showed everyone that she does.
"Getting to work with her in this really short period of time, I recognized a lot of talent and potential that she has," he added. "I told her I thought she could have gone all the way."
