Martha Mier's jazz Raggs and Blues book

[johand]

Hello,

I registered here to ask some question, before buying the app.
My piano teachers said that there are some app that create a band to play along with your piano practise. I found this app.
Currentky, i am learning some Martha Mier's jazz Raggs and Blues song from book 1. http://www.alfred.com/Products/A--00-6642.aspx

Are these song already in the library to download? If yes, where can i find them. If no, would anyone be so kind to put in the "Just Struttin Along" and "Ragtime Do Si Do"
if you pm me your email, i can send you the piano score (very short)

many thanks, Johan
