Well, since we're all so into it -- The guys who I heard singing this were doing it in 4, and the changes were:

[1]Rolling home, rolling home Rolling home across the [4]sea Rolling [5]home to old [1]New England Rolling home dear [5]land to [1]thee.

I can hear the melody in my head. Are the verses the same melody as the chorus? If so, I know the song now...lucky boy me.
