i like the song "the star and stripes forever" and i would like to play this song at the piano. Does anyone know the most difficult version of the piano score of this song? and where i can buy it? i am in hong kong and there are so few music books here. i think i have to purchase in the net. i don`t mind playing it a little bit in jazz style, however, i want to play difficult version instead of easy one ,i like challenge.
