JINGLE BELLS, as most (if not all) American readers will know, is not actually a Christmas song. Well, it is now, of course, but didn't start out that way. Originally (and this is for British readers), it was a Thanksgiving song called ONE HORSE OPEN SLEIGH. We don't observe that celebration on this side of the pond though, so we've always associated it with the Yuletide season.
The original version had five verses, two of which are now commonly ignored as they don't really lend themselves to the song's adopted Christmas theme.
Anyway, here's the velvet-voiced JIM REEVES with his rendition. Everybody sing along now.
