Yes, "Call Me Darling" is missing   though  it's in the booklet's discography and discussed in the notes. But where did you get the list you cite?  Also my Apple Music player says there are 24 cuts on the disc, the last being "Error-short repeat of Kansas City Stride". Fortunately I have "Call Me Darling" on VJC-1018 which Mosaic lists as their source.  Old age is catching up with me. I figured it out just as I turned on my computer to read responses.

If anyone is interested, I have some digitized live broadcasts of Ken Peplowski that are not commercially issued: Hotel Four Queens, Las Vegas 8/2/1993 Newport Jazz Festival with Evan Christopher and Anat Cohen 8/4/2012    

Got this today, very much looking forward to listen to it now:

IIRC he was the brother of actor Taylor Negron.
