Torchwood: Disco

It's 1987 and "Disco" Jones is still dancing. Life and soul, bab, life and soul. Wednesdays is darts at The Merry Miller, Thursdays - shove ha'penny at The Boilermakers, Fridays played by ear, and Saturdays it's the Disco at Cinderella's.

So who is Tom and why does he want to build a fence with him?
