You Really Got Me

"You Really Got Me" was a song playing on a nearby handheld radio when Maria Jackson, having been transported back in time from the early 21st century, encountered a young Sarah Jane Smith on 13 July 1964. (TV: Whatever Happened to Sarah Jane?)

Behind the scenes
In the real world, the single was released on 4 August of that same year, nearly a month after the events of Whatever Happened to, so it would have been impossible for it to have been playing on the radio.
