This is believed to have been a "spur of the moment" after dinner speech. Sometimes referred to as an Extempore
O thou, in whom we live and move-
Who made the sea and shore;
Thy goodness constantly we prove,
And grateful would adore;
And, if it please Thee, Power above!
Still grant us, with such store,
The friend we trust, the fair we love-
And we desire no more. Amen!
