Sourcing[]
Because the credit did not appear until season 8, it would be helpful if some kind of source could be given for the first seven seasons. Anyone know where we got that information? CzechOut ☎ | ✍ 11:54, March 24, 2010 (UTC)
- The information seems to come from The Television Companion (I've just checked for The Daleks and that's the same info, it's incidentally also one of the sources on the BBC's episode guide page (the other being the The Discontinuity Guide).
