Steve points out that "Hot Lips" is also the last recording of Red Nichols. As you can see in page 567 in the previous posting, "Hot Lips" was recorded in Dec 1964 and issued as a 45 rpm record, Magnolia MS 1071.
It is noteworthy that Steve and his dad Stan are working hard on the definitive book about Red Nichols's life and music. It is unlikely I can help with the book since Stan and Steve are the experts. But if there is anything I can do, I'll be very happy -and honored- to assist.
