I remember a big chunk of it, but it seems like a verse may be missing.

ahem.... mi mi mi mi miiii

a boy took a girl in a little canoe when the moon was shining all around and as he plyed his paddle you couldn't even hear a sound so they talked and they talked til the moon grew dim he said you better kiss me or get out and swim so what you gonna do in a little canoe **when the moon is shining all around?

(repeat until **) when the moon is shining all-a, boys are paddling all-a, girls are swimming all around.
