Someone changed the writer credit to Tom MacRae, which is a bit silly considering there's a very clear on-screen writing credit for Steven Moffat at the top of the short. --Ben Paddon talk to me 23:16, January 7, 2012 (UTC)
The Small Print on the Series 6 Boxset Leaflet, that comes with the Series 6 DVD and Blu-ray Boxset, says "CORRECTION: The additional scene "Up All Night" has incorrectly been credited on screen. It was written by Tom MacRae, rather than Steven Moffat", so Tom MacRae DID write this story, so it is not "Silly" that it was changed. A-6012 19:25, January 8, 2012 (GMT)
