I Can't Find Jimmy Boyd Singing "Santa Claus Blues" / "I Saw Mommy Do the Mambo" Page

You can help me locate either a better analog copy or a digital copy from the original master tapes of two songs.  I looked in many of the online stores and have checked for Jimmy Boyd web pages where the web master might know where the recordings can be located.  My best hope is to find a CD containing these songs.  The basic lyrics and MP3 files of Santa Claus Blues can be found at this page.  Any information you can pass to me would be greatly appreciated at cla@netzero.net.  Last Christmas I did find a CD entitled "Mambo Santa Mambo" which does have "I Saw Mommy Do the Mambo".  I have yet to purchase the CD, but other buyer's reviews are positive.  All the information I have is listed below with JPG's of the record labels.  The strange colors of this page mimic the colors of the record label  Thank you for your help.
