[Tony in Hawaii]

The flat-out best version of Jingle Bells was performed by Italian opera tenor Jose Carreras on his TV special years ago.
(Carreras is the "other guy" in the Three Tenors) The most memorable line was:

"On a one-a horse-a open sleigh"

[Citizen of the Savage Nation]

I was referring to any version of Jingle Bells sung by anything other than an actual adult human voice, ala jingle cats, jingle dogs, jingle babies, etc etc and freakin etc...the real Jingle Bells is a classic.
