From a Russian-language blog of some sort, lyrics to "Magic Works" and "Do the Hippogriff" (corrected for English punctuation and spelling):
Magic Works
Dance your final dance
This is your final chance
To hold the one you love
You know you’ve waited
Long enough
So believe that magic works
Don’t be afraid I'll be in hurt
Don’t let this magic die
The answers there
Oh, just look in her eyes
And make your final move
Hmmm don’t be scared
She wants you to
Yeah it's hard
You must be brave
Don’t let this moment slip away
So believe that magic works
Don’t be afraid, afraid I’ll be in hurt
Don’t let this magic die
The answers there
Just look in her eyes
And Don’t believe that magic can die,
No no no this magic can't die
So dance your final dance,
‘Cause this is your final chance
DO THE HIPPOGRIFF
All right Hogwarts… are you ready for some real music?
I said, ARE YOU READY?
ARE YOU READY?
I gotta hear ya… all right.
Come on, I wanna see your hands in the air.
We’re going to teach you a brand new dance tonight.
So move your body
You gotta help us Hogwarts
Together we can do this thing
Are you ready?
ARE YOU READY?
Move your body like a hairy troll
a learning to rock and roll
I spin around like a crazy elf
a dancing by himself
I boogie down like a unicorn
I brew a storm 'til the break of dawn
a put your hands in the air
Like an ogre just don’t care
CHORUS
Can you dance the hippogriff
Mama ma mama ma mama ma
Flying off from the cliff
Mama ma mama ma mama ma
Swooping down to the ground
Mama ma mama ma mama ma
Wheel around and around and around
Mama ma mama ma mama ma
OH!
Move around like a scary ghost
Who’s spooking himself the most
Shake your booty like a boggart in pain
Again and again and again
Get it on like an angry specter
Whose definitely out to get ya
Step your feet like a leprechaun
Get it on, get it on
CHORUS
