I learned it as:

Oh Soldier, soldier won't you marry me,
with your musket, fife and drum?
Oh no, sweet maid, I cannot marry thee,
For I have no (coat, shows, etc.) to put on.
So up she went to her grandfather's chest
and she got him a (coat) of the very, very best
Yes, she got him a (coat) of the very, very best
and the soldier put it on.

Eventuually he says Oh, no sweet maid I cannot marry thee for I have a wife of my own!"
