I'll give you a two-fer:

From the Land of Sky Blue Waters (waters)
From the land of pines, lofty balsams
Comes the beer refresing
Hamm's the beer refreshing
Hamm's.

or, (different tune)

From the Land of Sky Blue Waters
Capturing the frosty refreshment (?)
Hamm's Beer
Refreshing Hamm's Beer.

I've got some good Blatz and Schlitz commercials, if you want more....
