Lauren's was contemporary (sorry, forgot to add)
Saffron's was a waft tribute to her grandparents #NanwarzSupreme
Emma's was Fosse bowler hats (PCD cover of right now)
Greg's was Dad Dancing Disco
Dan's had benchography but was otherwise a generic freestyle
John's was a contempowaft
Nige's was dicky dancing wafty smooth
They stopped saying which of the styles it was (street commersh/jazz/contempowaft) series 19 when it became anything goes with Greg and then Dan.
Lauren looked to the sky, as did Greg
(As did Will to his Dad but not in his street routine, Jade's homage to her dead sister was AS as Greg had nicked the disco. Ugo and Judy's losses were mentioned but not homaged per se).
