High school talent show..need some help/advice!

[♂ÇRÅßßÿ®]

Okay, so a friend and I are going to sing a song in my schools talent show.
We are either doing
"Think about it, think, think about it. " - Flight of the Conchords
or
"Hiphopopotamus vs. Rymenoceros" - Flight of the Conchords.

I have the original songs but...I wanna get just the music but no lyrics. I am not sure how to go about doing this. I don't think they sell the music anywhere, and I am not sure if someone could rip the singing out?

Could someone please hit me up with some ideas, the tryouts are this friday!
Thanks!

P.S. If you need the songs, just say so I can give them to you.

You should sing the song "F&*kin the principle's wife" By Don-Givuh-Fuq. Its a classic for any highschool event.
