I Saw Three Ships lyrics

I saw three ships come sailing in
On Christmas Day, on Christmas Day;
I saw three ships come sailing in
On Christmas Day in the morning.

And what was in those ships all three,
On Christmas Day, on Christmas Day?
And what was in those ships all three,
On Christmas Day in the morning?
[ Lyrics from: http://www.lyricsmode.com/lyrics/c/chicago/i_saw_three_ships.html ]
Twas peace on earth that came to be
On Christmas Day, on Christmas Day;
Twas peace on earth that came to be,
On Christmas Day in the morning.

And all the bells on earth shall ring,
On Christmas Day, on Christmas Day;
And all the bells on earth shall ring,
On Christmas Day in the morning.
