Can't find piano sheet for this piece

[R] I'm doing a concert with a group on June 27th and I play the piano and we have to play "So Payaso" by Extremoduro, and this song has a lot of melodic details by piano which I would like to do. However, when I search for music sheets, I only find full piano covers for the song, and since I'm playing with a group I'd like to just have the actual piano parts of the song without the rest of things, could anyone help me somehow? Thank you guys so much
