When Jimmy Stewart guested on Bing Crosby’s radio show on March 19, 1952, he, Bing and Fran Warren sang a short rendition of Mississippi Mud (Harry Barris/James Cavanaugh). This was edited from the show and released on several Bing Crosby compilation albums. The entire segment lasts only 51-seconds and begins with Jimmy saying, “Hey Bing…Bing…What… What…What was that…What was that mud song you used to sing all the time?” Bing sings a line, Fran sings a line which ends with Jimmy singing “chewin’ on a cud,” and all three singing on the chorus.
