Well done, Mbo and Osmium!! And MMario -- where's the rest of that song? You have a great beginning there, keep on going!

OK, on behalf of the Lady Mudcats everywhere, here's my offering for this CHALLENGE!:

The Tale Of The Mardi Gras Queen
(Tune: Almost Every Circumstance)

Chorus:
Seven days are in the week
They're written on me underpants
There's four hundred fellas in the crowd
A lookin' up at me
Oh, but never let go of the float
When you're tossin' out your Sunday best
There's many a poor girl threw away
Her chance matrimonee

The first time I saw me love
Twas outside of the Pub O'Dowd
And the second time I saw him
Twas in front of La Jollie
He was jumpin' up and down with might
A tryin' to catch me purple pair
But I can tell you now me girls
The poor lad missed 'em twice!

Seven days are in the week
They're written on me underpants
There's four hundred fellas in the crowd
A lookin' up at me
Oh, but never let go of the float
When you're tossin' out your Sunday best
There's many a poor girl threw away
Her chance matrimonee

My love he took off at a pace
Twould bring pride to a racehorse
And he turned the corner at St. Paul
Just to catch up with me
Well, I'd never seen him run so fast
And frankly it was quite a sight
But I can tell you now me girls
The poor lad fell down thrice!

Seven days are in the week
They're written on me underpants
There's four hundred fellas in the crowd
A lookin' up at me
Oh, but never let go of the float
When you're tossin' out your Sunday best
There's many a poor girl threw away
Her chance matrimonee

Well, the last time I saw me love
He was pushin' through the drunken crowd
And I felt so sorry for him
I let go me posin' post
And the float it hit a pothole
And caused me feet to slip and slide
And I can tell you now me girls
Not a darn thing I could hide!

Seven days are in the week
They're written on me underpants
There's four hundred fellas in the crowd
A lookin' up at me
Oh, but never let go of the float
When you're tossin' out your Sunday best
There's many a poor girl threw away
Her chance matrimonee
