The 1930s and 1940s were the peak years of radio and of course everyone wanted to hear Bing sing, especially during the war years. He was the top movie and recording star of the era. On radio his Kraft Music Hall sometimes attracted audiences of almost 50 million! Guests ranged from opera singers to comedians. We've selected songs from the period 1938 to 1946. None were recorded by Bing commercially. Bing often sang duets and two examples - with Connee Boswell and Marilyn Maxwell are included. These tracks were nearly lost. In the 1960s Eddie Rice, a Crosby fan, visited John Scott Trotter who had led the Kraft orchestra. John Scott revealed that acetates of many of the songs were stored on discs under the floorboards at his home. Rice persuaded Trotter to release the discs. Careful remastering followed. To call them a revelation would be an understatement.
