Both Steve and Jerry responded promptly and with information. Thanks, guys.
Steve: I listened to the youtube. This is not Red Nichols. The trumpet reminds me of Walter Holzhaus of Willard Robison's band. (Who at times was thought to sound like Red.) Willard Robison recorded Deliruim for Perfect/Pathe (c.8/8/27)...I've never heard that record. This version isn't the California Ramblers' version for Plaza.
Jerry: I can find nothing documenting that the tune "Delirium" was recorded by Edison. The recording in youtube is almost 4 min long. The California Ramblers is only 3:03. Listen
