I don't know about the church context, I guess it would depend on the attitude of the congregation & minister, but as a harvest song I find this one has a certain appeal (from the singing of Bill Whaley & Dave Fletcher):

Stixwould Harvest Song
STIXWOULD HARVEST SONG (Drink Good Ale)

Drink good ale, drink the barrel dry,
Yonder field is where I've been,
I tore my shirt, and I tore my skin,
But I've got my master's harvest in,
So drink good ale.

Drink good ale, drink the barrel dry,
Harvest in, and harvest home,
The farmer can no longer moan,
We'll get a fat hen, and a bacon bone,
So drink good ale.

Drink good ale, drink the barrel dry,
Farmer, he has got his corn,
It's all well mown, and it's all well shorn,
We work each day from the break of dawn,
So drink good ale.

Drink good ale, drink the barrel dry,
Harvest has come home at last,
It's never turned over, and it's never stuck fast,
It's fuller than ever it was in the past,
So drink good ale.
