Spice Girls
From Tardis Wiki, the free Doctor Who reference
The Spice Girls were a musicial group. K9 played their music for Sarah Jane Smith when she was staying at Cornflower Cottage. (PROSE: The Sow in Rut)
In 1997, the Spice Girls attended the press conference covering the Mars mission. (PROSE: The Dying Days)
The Eighth Doctor, in an attempt to tell Sam Jones that she looked "cool" in her Victorian clothes, said she'd be the 1890s equivalent of a Spice Girl. Sam decided to take that as a compliment. (PROSE: The Bodysnatchers) Sam later thought that the sound of Daleks trying to sing would be worse than the Spice Girls. (PROSE: War of the Daleks)
