Three Dog Night (unproduced home video)
From Tardis Wiki, the free Doctor Who reference
Three Dog Night was a pitch Paul Cornell wrote for Dreamwatch Media following Return of the Sontarans involving three K-9s. It involved the Hellfire Club, an attempt to return Britain to the 18th Century. It was a re-hash of a plot Paul Cornell had used for Jason Haigh-Ellery's female Doctor audio play, starring Jo Ware.
