You are gonna' have to provide a little more info. I searched "maid" "maide" and "fifeo" in Deadbase and there were no matches for song titles containing any of those words. Other possible titles or spellings?

That which you seek may be the Bonnie Lass of Fyvie-o, a folk song also known as Fennario. Peggy-O is a variant of this and although Deadbase does not mention it, the Setlists site returns two hits on 'Fennario'

05/25/95- Memorial Stadium - Seattle, WA
06/04/95- Shoreline Amphitheatre - Mountain View, CA

Whether the Dead sang a different version in those shows or any others I do not know

Here is one version

There once was a troop o' Irish dragoons
Cam marching doon through Fyvie-o
And the captains fall in love wi' a very bonnie lass
And her name it was cad pretty Peggy-o

There's many a bonnie lass in the Howe o Auchterless
There's many a bonnie lass in the Garioch
There's many a bonnie Jean in the streets of Aiberdeen
But the floor o' them aw lyes in Fyvie-o

O come doon the stairs, Pretty Peggy, my dear
Come doon the stairs, Pretty Peggy-o
Come doon the stairs, comb back your yellow hair
Bid a long farewell to your mammy-o

It's braw, aye it's braw, a captain's lady for to be
And it's braw to be a captain's lady-o
It's braw to ride around and to follow the camp
And to ride when your captain he is ready-o

O I'll give you ribbons, love, and I'll give you rings
I'll give you a necklace of amber-o
I'll give you a silken petticoat with flounces to the knee
If you'll convey me doon to your chamber-o

What would your mother think if she heard the guineas clink
And saw the haut-boys marching all before you o
O little would she think gin she heard the guineas clink
If I followed a soldier laddie-o

I never did intend a soldier's lady for to be
A soldier shall never enjoy me-o
I never did intend to gae tae a foreign land
And I never will marry a soldier-o

I'll drink nae more o your claret wine
I'll drink nae more o your glasses-o
Tomorrow is the day when we maun ride away
So farewell tae your Fyvie lasses-o

The colonel he cried, mount, boys, mount, boys, mount
The captain, he cried, tarry-o
O tarry yet a while, just another day or twa
Til I see if the bonnie lass will marry-o

Twas in the early morning, when we marched awa
And O but the captain he was sorry-o
The drums they did beat o'er the bonnie braes o' Gight
And the band played the bonnie lass of Fyvie-o

Long ere we came to the Howe of Auchterless
We had our captain to carry-o
And long ere we won into the streets of Aberdeen
We had our captain to bury-o

Green grow the birks on bonnie Ythanside
And low lie the lowlands of Fyvie-o
The captain's name was Ned and he died for a maid
He died for the bonnie lass of Fyvie-o

OK, I'm confused now.
Peggy-O is an extremely common song for the Dead. Some setlists show it as Fennario but it still sounds like Peggy-O to me.

Sorry I can't help.

It's time to reissue Bob Weir's Ace as a remasterd HDCD with bonus tracks

This show's a no brainer! Would love an official copy!
