Another radio program aimed at five- to fourteen-year-olds, "The League of Ovaltineys", was broadcast to Great Britain by Radio Luxembourg on Sunday evenings at 5:30 PM. Beginning in February 1935, it was broadcast until September 1939, when the outbreak of World War II forced closure of the station, and again after the war from 1952. As with the U.S. program, listeners could obtain badges, pins, and secret codes. The Ovaltineys' advertising jingle was regarded as one of the most successful jingles of the era, and featured the popular English singing trio The Beverley Sisters.
