In 1940, at 8:47 PM, the New Regency Theatre in London, which was owned and operated by the late Henry Gordon Jago in the 1890s, was destroyed in the Blitz. The hotel next to it was also destroyed but it was evacuated 47 minutes earlier, meaning that no one was killed. (AUDIO: Swan Song)

In 1979, Beep the Meep travelled to a parallel universe, in which the Doctor's universe existed only as part of a BBC science fiction television series called Doctor Who, and took control of the BBC Television Centre. The Eighth Doctor and his companion Izzy Sinclair defeated Beep with the help of the actor Tom Baker, who infuriated him with his endless rambling. Strangely, Baker both physically resembled the Fourth Doctor and played him on the television series. The Doctor learned the truth when he discovered the first issue of Doctor Who Weekly.

On Hex's 23rd birthday in 2021, his friend Damien Boyd died at St Gart's Brookside Hospital, where Hex worked.

Ace went undercover there to investigate its "C-Programme" and its possible connection to the Cybermen. Hex eventually joined the duo to help. Hex's help with the Cyber-threat earned him a place in the TARDIS once it was overcome. (AUDIO: The Harvest)
