A Good Man Goes to War
In the "Doctor Who" episode "A Good Man Goes to War", River Song encounters Rory Williams as she is returning to her cell in the Stormcage Containment Facility. She tells him that she has just been to 1814 for the last of the Great Frost Fairs. The Doctor had taken her there for ice-skating on the river Thames. "He got Stevie Wonder to sing for me under London Bridge," she says. When Rory expresses surprise that Stevie Wonder sang in 1814, River cautions him that he must never tell the singer that he did.
