According to discographies, this was unissued. (Maybe Glenn has a test pressing?) Forget about the poor vocal (banjoist Art Jarrett) and listen to the sax solo at 2:14. Does the soloist sound like Trumbauer to you? It does to me. The alto sax players in this recording were Dick Cunliffe and Don Watt.
And here is the 1930 Ted Weems recording of Slap that Bass. Listen for the short trumpet solo at 2:10.
Do you think that Art Weems or Merrill Conner (the two trumpet players in this recording) display a Bixian influence? I certainly do. According to discographies, the string bassist is Country Washburn.
