According to the Bing Crosby Discography at
http://www.kcmetro.cc.mo.us/pennvalley/Biology/lewis/crosby/disco.htm
Louis Armstrong and Bing Crosby had a long professional relationship, starting in the
1936 with their recording "Pennies from Heaven" (listed as Frances Langford, Louis
Armstrong, Jimmy Dorsey Orchestra) and continuing through 1960 (recordings with the
Billy May Orchestra and Louis Armstrong).
Who else can claim to have recorded with Paul Whiteman and David Bowie?
The two tracks Crosby recorded with Grady Martin, "Just a Little Lovin' " and "Till
the End of the World", can be found on AWAY BACK WEST AGAIN (Collector Series) 1939-up
Volumes 20 and 87 by the American Gramophone & Wireless Co. (see
