I did a search for come to the fair together with taylor, I think.  I knew it was a composed song, so I didn't look at the Ballad Index, but a search for the song title took me there anyway, which is where I found the composers' names.  I remember it only vaguely from childhood, so I have no idea what the right words would be; I'm guessing that Terry Kluytmans changed them a bit so that he could claim a copyright, but I could easily be wrong about that.
