My dad used to sing this when I was growing up. Can't be assured of the lyrics, but it includes a little more than I've seen posted.

In the 1814 we took a little trip
Along with Colonel Jackson down the Mighty Mississip'
We took a little bacon and we took a little beans
And we fought the bloody British through the town of New Orleans

Well Old Hickory said we could take 'em by surprise
If we didn't fire muskets till we looked 'em in the eyes
Held our fire till we saw their faces well
Then we lifted up our squirrel guns and blew 'em all to...

Well we fired our guns but the British kept 'a comin'
But there was a(uh)not as many as there was a while ago
Ran so fast that the hounds couldn't catch 'em
On down the Mississippi to the Gulf of Mexico
