Free Music Scores

I was looking aroud the web for a/any piece of music by Erik Satie. I ended up a one site, which refered me a 2nd site. Both of these sites were "free". The secound site where I found the Gymnopédie No. 1 by Satie there was a problem with the PDF provided it was missing the 1st page. The problem was this was "free" site. After trying to reload the faulty PDF as was told. I would to pay to get membership. Finally after several days I went to wiki as should have done from the begining. From there I connected to something called Mutopia, music+upotopia?, and I find the piece(s) I am looking for.

However I still have a problem. The piece that I get is not really scored for a piano. Just look at bars 5-6 on the except above. The right hand has to sustain a chord AND play an octave above the highest note in the chord. I think that this, as it is scored, is really a piano/flute peice. remember Hinterland Who's Who those short nature films put out Enviroment Canada. This piece of music played in the backgroud.
