These are the correct chords and are good for the piano intro. There is no piano in the 
or the last verse, the guitar plays bar chords though.

The 5 behind a chrod just means bar chord. They could be played as a full chord, just 
that some will be minor.

(piano intro)

                 Emaj7       F#m
Just hear those sleigh bells jingling
Abm       A        Emaj7
Ring ting tingling too

    Abm         A            Emaj7

And sing a chorus or two
Come on, it's lovely weather
For a sleigh ride together with you
