How To Take Out Marimba, And Keep Piano?

Excuse me if I should post this at the education forum, or if the answer is right in front of me. I’m quite new to audacity, only used it once. Please explain everything as I don’t know how to use Audacity very much.

I have a solo upcoming in Band class, I will be performing ‘Scrumpy’ on the Marimba. The only problem is, I don’t have someone to play the piano with the song, nor do I even have the music for it. I found a few videos of someone performing the song on the bells or marimba on YouTube. and

Is it possible to take the MP3 song, and edit out the marimba using Audacity, that way I have the piano by itself? How would I do it?

No, Audacity can’t do that.
