Let me set the record straight right now. I am not a fan of High School Musical. I am a fan of Harry Potter. This fic may offend fans of both. This idea spawned when I was babysitting some young children who insisted on watching High School Musical.

I don't own the book, the refrenced movie, or the song; this is just for fun. Anyone who wants to make suggestions or requests for a song, please feel free to submit them. Enjoy.

This takes place in an 5th year without the Umbridge problem, so I guess its AU.

Albus Dumbledore paged through the last of many heavy tomes. He had been researching in the beginning of the summer to create a new spell, and he was all but finished.

He had become inspired when he went to a Muggle born student's house to explain the wizard world and let them know about Hogwarts. It was there that he saw a film on the Muggle television set. He rarely paid attention to such things, but this particular movie was fascinating. It featured two teenagers who were in love, though the groups they hung out in were opposed to the relationship. It was very similar to the separated house issue he tried time and again to resolve.

That's where the film had been so inspirational. All the characters sang about their feelings and eventually they used to power of music to become unified. And he adored all the dancing.

After seeing this life changing movie, he went straight to his books and began to research the means to make a spell that would work as this film did to unite the houses.

It had taken months, but now his spell was ready. When the Sorting Feast had been completed, he had closed himself off in his office to put the final touches on the spell. Once it was ready, he climbed to the highest astronomy tower and began to read his spell.

At the end of the spell he felt a muted pulse beat out from his wand and cover the entire school and grounds. Dumbledore smiled. After so many years, the houses of Hogwarts would be unified.

The next morning something was terribly wrong. All the faculty, with the exception of Dumbledore, watched as both themselves and the students kept breaking into song throughout breakfast.

"I blame those Weasley twins," Snape muttered with distaste, clinging to a hot mug of coffee.

"Severus," Minervra scolded, "we can't just blame those two when something odd happens. Once Dumbledore wakes up I'm sure we'll be able to get to the bottom of this."

Snape muttered something into his coffee which sounded very much like, "First time the old man oversleeps and this happens. Just brilliant."

Minervra refrained from scolding the other professor, as she was pondering the coincidence as well.

Ron Weasley was freaked out. Harry and Hermione were taking that mornings occurrences in stride, but he was still trying to recover from shock of Neville bounding into the boys' bath while singing something about what a beautiful morning it was.

"Ron, I'm sure whatever is wrong will be sorted out soon," Hermione rolled her eyes.

"Oh sure, you stay calm. For all we know this could be You-Know-Who, or evil spiders, or a Howler gone evil, or my brothers…"

"Ron, I'm sure Dumbledore will figure this all out soon enough," Harry tried to calm down the red head.

"Though some of those theories seem well grounded, the You-Know-Who one at least, I've begun to generate some theories as well," Hermione chimed in.

"I've got a theory," Ron began to sing,

"That it's a demon

A dancing demon

No, something isn't right there."

Before she could stop herself, Hermione found herself beginning to sing along to Ron's song,

"I've got a theory

Some kid is dreaming

And we're all stuck inside

His wacky Broadway nightmare."

Harry had watched as his two friends had broken into song. He wanted to tell the just to calm down and quit with the music, but when he opened his mouth singing came out instead,

"I've got a theory

We should work this out

It's getting eery

Whats all this cheery

Singing all about?

Ron jumped in with a new theory, but soon started rambling in tune after a glare from Hermione,

"It could be witches,
Some evil witches,
Which is ridiculous ,
'Cause witches they were persecuted,
Wicca good, and love the Earth,
And woman power,
And I'll be over here."

He slumped lower on the bench to hide from the glares of both Hermione and any other female within hearing range.

As professor Trelawney made her way by, she added in,

"I've got a theory,

It could be bunnies.

Bunnies aren't just cute like everybody supposes
They got them hoppy legs and twitchy little noses
And what's with all the carrots
What do they need such good eyesight for anyways?
Bunnies!
Bunnies!
It must be bunnies!
Or maybe midgets..."

Hermione rolled her eyes as she continued,

"I've got a theory
We should work this fast
Because it clearly could get serious
Before it's passed"

Harry placed his music laced theory before his friends,

"I've got a theory
It doesn't matter
What can't we face if we're together?
What's in this place that we can't weather?
Voldemort?
We've all been there...
The same old tricks...
Why should we care?"

The trio found themselves joining hands as they sang together,

"What can't we do if we get in it?
We'll work it through within a minute
We have to try,
We'll pay the price,
It's do or die..."

"I've nearly died twice," Harry chimed in.

"What can't we face if we're together?"

"What can't we face?" Hermione sang out.

"What's in this place that we can't weather?"

"We're together!" Ron chimed, a look of relief coming over him.

"There's nothing we can't face."

"Except for bunnies," Trelawney reminded them sadly, before drifting from the Great Hall.

The trio exchanged worried glances once there song was over.

"What the hell was that?" Harry asked.

"Sure, now your freaking out," Ron muttered.

Hermione got up, "I'm going to the library. We need to research this. It would be too dangerous right now if everyone sings their thoughts and emotions. If You-Know-Who finds anything out because one of us sings about the Order…" She didn't finish the thought.

"I'll see you in class then, I'll see what Dumbledore knows," Harry got up and followed the witch out the door.

Ron watched both of them leave. "What am I supposed to do?" He grabbed some bacon and went to the door, muttering, "Now I have that song stuck in my head."

Well thats the first chapter. Let me know what you think.

The song used for this chapter is "I've got a Theory" from the Buffy the Vampire Slayer episode "Once More with Feeling" minus the one or two edits I made to make it fit potter verse. I suggest findins it on youtube if you've never heard it before.
