早教英語兒歌：I saw three ships

I saw three ships come sailing by
    sailing by, sailing by
    I saw three ships come sailing by
    On Christmas day in the morning.
    And what do you think what's in them
    in them, in them
    And what do you think what's in them
    On Christmas day in the morning.
    I saw three ships come sailing by
    sailing by, sailing by
    I saw three ships come sailing by
    On Christmas day in the morning.
    On Christmas day in the morning.
