Through the Keyhole

Through the Keyhole was a television programme that gave an inside look into celebrities' houses. It was hosted by David and one other.

In April 1992, the Doctor's TARDIS was the subject of inspection, specifically his bedroom and the Cloister Bell. This appearance heralded the Doctor's first return to television screens after a substantial break. (NOTVALID: The Year Ahead)
