Okay, let's get this party started. To celebrate Christmas In July, here's Sammy Kaye's Christmas Serenade a 10" LP from Columbia Records (CL 2541). I haven't been able to track down a recording date for this LP, but Ernie Not Bert's blog shared an album with the same name last year (though with different contents). That LP was dated 1951 (see link).
This is a mix of fun tunes with more serious choral renditions. I hope Kaye's variations of "Santa Claus is Comin' to Town", "Jingle Bells" and "Winter Wonderland" make it into your Christmas music rotation come November!
