Task: Question Generation
Input (English): Passage: Stafford continued to record. She duetted with Gordon MacRae on a number of songs. In 1948, their version of "Say Something Sweet to Your Sweetheart" sold over a million copies. The following year, they repeated their success with "My Happiness", and Stafford and MacRae recorded "Whispering Hope" together. Stafford began hosting a weekly program on Radio Luxembourg in 1950; working unpaid, she recorded the voice portions of the shows in Hollywood. At the time, she was hosting Club Fifteen with Bob Crosby for Columbia Broadcasting System (CBS) radio.Weston moved from Capitol to Columbia Records and, in 1950, Stafford followed suit. Content and very comfortable working with him, Stafford had had a clause inserted in her contract with Capitol stating that if Weston left that label, she would automatically be released from her obligations to them. When that happened, Capitol wanted Stafford to record eight more songs before December 15, 1950, and she found herself in the unusual situation of simultaneously working for two competing record companies, an instance that was very rare in an industry where musicians were seen as assets. In 1954, Stafford became the second artist after Bing Crosby to sell 25 million records for Columbia. She was presented with a diamond-studded disc to mark the occasion.In 1950, Stafford began working for Voice of America (VOA), the U.S. government broadcaster transmitting programmes overseas to undermine the influence of communism. She presented a weekly show that aired in Eastern Europe, and Collier's magazine published an article about the program in its April 21, 1951 issue that discussed her worldwide popularity, including in countries behind the Iron Curtain. The article, titled "Jo Stafford: Her Songs Upset Joe Stalin", earned her the wrath of the U.S. Communist Daily Worker newspaper, which published a column critical of Stafford and VOA.
