Ok, so I felt guilty urging y'all on without making my own contribution. Here it is, for what it's worth:

Micca brings the whiskey over
Micca brings the whiskey over
He's done forgot what a groundhog's for
Oh Groundhog!

Caitrin passes the cookies out
Caitrin passes the cookies out
But the groundhog's turning up his snout
Oh Groundhog!

Alison whistles up a tune
Alison whistles up a tune
See the groundhog dancin' 'neath the moon
Oh Groundhog!

Amos pens another song
Amos pens another song
But the groundhog thinks he takes too long
Oh Groundhog!

Catspaw plays his pickle kazoo
Catspaw plays his pickle kazoo
Then he drops it down the loo
Oh Groundhog!

Áine writes it down in Irish
Áine writes it down in Irish
But Philippa thinks it's much too stylish
Oh Groundhog!
