In London, a woman named Margaret visits the subway daily, sitting at the dock just to hear the “Mind the Gap” announcement recorded by her late husband, Oswald Laurence, in the 1950s. Oswald, an actor, recorded this famous warning for the London Underground. After his passing in 2007, Margaret found comfort in hearing his voice at the Embankment Tube station. When the original recording was replaced in 2012, she requested it back, and Transport for London honored her request by reinstating his voice in 2013. His announcement continues to play today, a tribute to their lasting connection.
