Nelson's site, like most sources I've seen, gives two verses of this song. An 1811 songster that comes down to me from my great grandfather includes a third:

Utawa's tide, this trembling moon,
Shall see us float over thy surges soon;
Saint of this green isle, hear our pray'rs,
Oh, grant us cool heavens, and favoring airs.
Blow breezes, blow, etc...

Any Moore scholars have opinions on its authenticity ?
