I'll pull my hat to tumty tum.
My ears will be no bolder.
I'm going down to Shiloh town,
and there I'll be a soldier.

I'll keep your letter near by heart.
I'll see you when I'm older.
I'm going down to Shiloh town,
and there I'll be a soldier.

If you're willing to folk process that first verse, it could become:

I'll pull my hat to hide my hair,
My ears will be no bolder...
