‘Flagship’ (monthly) episodes of The Doctor Who Show and many of its off-shoots (eg: episodes of Alternate Galaxies) are hosted by Rob Irwin (@theDWshow) in Sydney, Australia and Dave Kitchen (@DkWedgetail) in Melbourne, Australia. Occasionally, they are joined by guest co-hosts such as Mike Solko and Richard Nolan. Over the years, standalone shows have also dropped on the feed. UK author Iain Martin (@theIainMartin), for example, flies solo at present with his irreverent Doctor Who A-Z episodes.
