Hi,

I'm currently playing the piece named "La Cumparsita" on piano and using this sheet here: http://imslp.org/wiki/La_Cumparsita_%28Matos_Rodr%C3%ADguez,_Gerardo_Hern%C3%A1n%29
However, I have noticed that so many people on Youtube for example are playing different versions of the piece which I guess is arrangements. I have been searching for hours to find an arrangement sheet like these for piano but didn't find anything:

I have also noticed that several people are playing the same arrangements but you can still not find the sheets anywhere. Why? Any ideas?

Thanks to all of you! :-)
