Even though Jingle Bells was written for Thanksgiving, Christmas calls it it's own now. Of all the times I've heard the song, there have been only 2 variations as far as the lyrics are concerned(and I'm talking the original version, not some pop modification). Some say "bob tailed nag" others "bob-tailed bay". And, "two-forty for" others, "two-forty as". Then I saw the 1949 cartoon, Snow Foolin'. The 2nd and 3rd verse was different. This version had the most drastic changes! Was this the only time that was done?
