Presenter and former music hall artist Margery Manners used her experience of getting sailors to sing along with her choruses to cheer workers and listeners.
Workers' Playtime was a touring show, with the Ministry of Labour choosing which factory canteens it would visit.
The BBC, for its part, was very happy to continue with a show which had proved a national success even if it did mean transporting crew, cable, microphones, two pianos, a producer, two pianists and a group of variety artists up and down the country three times a week.
Many famous variety, vocal and comedy artists appeared over the years, such as Charlie Chester, Bob and Alf Pearson, Peter Sellers, Tony Hancock, Frankie Howerd, Terry-Thomas, Anne Shelton, Betty Driver, Eve Boswell, Dorothy Squires, Arthur English, Julie Andrews, Morecambe and Wise, Peter Cavanagh, comedian George Martin, Janet Brown, Roy Hudd, comedian Michael Howard, harmonica player Paul Templar, The Stargazers, Bob Monkhouse, impressionist Peter Goodwright, Percy Edwards, Ken Dodd, Ken Platt, Gert and Daisy (Elsie and Doris Waters) and many more.
Regular musicians included James Moody (piano), Bert Weedon (guitar) and Max Abrams (drums).
