In Town Tonight was a BBC radio programme broadcast on Saturday evening from 1933 to 1960 (except for a period of 26 weeks in 1937 when The BBC presents the ABC was broadcast instead). It was an early example of the chat show, originally presented by Eric Maschwitz. Its theme music was the Knightsbridge March by Eric Coates. Its introductory sequence had a voice crying "Stop" to interrupt the sound of busy central London, before an announcer said "Once more we stop the mighty roar of London's traffic ..." At the end of the programme the voice would say "Carry on, London".
