AN: The song is Luck Be a Lady, from the musical Guys and Dolls.

Luck Be a Lady

There were what seemed like a million girls down by the oak tree, where Sirius and Remus happened to be dragging a certain James Potter.

When they finally reached their destination, Remus propped James up against the oak, and made sure that was where he staid. Sirius, on the other hand, was placing a Sonorus charm on himself.

"Alright, ladies!"

"And gentlemen!" a voice called from the crowd. The voice sounded suspiciously like Peter.

"Okay, and gentlemen. One of you will be lucky enough to win a date with James Potter here, and probably end up as his girlfriend!"

The girls were screaming and swooning at this point, and most were either staring, or trying to, dreamily at James.

"But first I must lay down some ground rules."

The girls all looked disappointed.

"Just listen," called Remus.

But he didn't finish before Sirius started singing.

All the girls who had been swooning at James, immediately turned their attention to drooling at Sirius.

"You have very devoted fan girls, Prongs," Remus muttered.

"Like I care."

They call you Lady Luck.

But there is room for doubt.

At times you have a very unladylike way of running out.

You're on a date with James.

The pickings have been lush,

And yet before this evening is over you might give him the rush.

You might forget your manners

You might refuse to stay

And so the best thing I can do is pray.

Luck be a lady tonight

Luck be a lady tonight

Luck if you've ever been a lady to begin with,

Luck be a lady tonight.

Luck let gentleman see,

How nice a dame you can be

I've seen the way you've treated other guys you've been with

Luck be a lady with James.

A lady doesn't leave her escort.

It isn't fair, it isn't nice

A lady doesn't wander all over the room,

And blow on some other guy's dice

So let's keep the party polite.

Never get out of his sight

Stick with him baby

He's the fellow you came in with,

Luck be a lady

Luck be a lady

Luck be a lady tonight.

Luck be a lady tonight

Luck be a lady tonight

Luck, if you've ever been a lady to begin with

Luck be a lady tonight.

Luck let a gentleman see

Luck let a gentleman see

How nice a dame you can be

How nice a dame you can be

I know the way you've treated other guys you been with,

Luck be a lady, a lady, be a lady with me.

Luck be a lady with me

A lady wouldn't flirt with strangers

She'd have a heart; she'd have a soul

A lady wouldn't make little snake eyes at James,

While he's got my life on this roll.

So let's keep the party polite

Let's keep the party polite

Never get out of his sight.

Here Remus and Peter took over the singing.

Never get out of his sight.

Stick here, baby, stick here, baby.

Stick with him baby,

He's the fellow you came in with

Luck be a lady

Luck be a lady

Luck be a lady tonight.

Coming out, coming out, coming out

Right!

The girls started screaming and swooning. Some lifted their shirts. Poor girls. Anything to get attention from the three hottest boys in school (Peter was dead ugly).

In the back of the crowd, Camilla was already planning her wedding, with a certain marauder.
