That's one I don't have! Capitol is famous for CD releases/rereleases featuring hidden tracks. I think every CD in the Ultra Lounge Christmas Cocktails series has them.
Some of the hidden tracks are tunes or spoken word greetings intended for record dealers from Capitol Records. The unknown version of Jingle Bells could well be one of these. Since they weren't released commercially they probably wouldn't have received a catalog number or show up on a session track list.
I think Tex Beneke did record for Capitol after his break from The Benny Goodman Orchestra so that's a good guess, HollyJolly. Mercer's a good bet too!
