Actually, you are wrong
or at least misled in your
a**ertion of the accuracy
of the lyrics for
Sweet Little Jesus Boy
on the Andy Williams
Christmas Album.
The third line from
the end as sung
by Andy Williams
is the following:
"Born long ago".......
Not "born a long ago."
No "a" prior to "long,"
which is silly and awkward
(even to sing) to saythe least.
Simply
listen to the song to hear
how Williams only uses
the 3 words set forth
above, and if the
writers of this version
of the song submitted
their lyrics with the silly
"a" included, thankfully
Mr. Williams corrected
the silliness in how he
sings it on his Christmas Album.
